## How Can A Projectile Fall Around The Earth?

A projectile can “fall around Earth” **if the distance it falls matches the curvature of Earth**.

## What causes a projectile to fall?

**Gravity** causes a vertical acceleration. The ball will drop vertically below its otherwise straight-line inertial path. … A projectile is an object upon which the only force is gravity. Gravity acts to influence the vertical motion of the projectile thus causing a vertical acceleration.

## What do we call a projectile that continually falls around Earth?

A projectile that continually “falls” around Earth is **a**. **satellite**. .

## What connection does Earth’s curvature have with the speed needed for a projectile to orbit Earth?

How does Earth’s curvature relate to the speed needed for a projectile to orbit around Earth? An object falls about 5 m in the 1st second on free fall the **Earth curves downward 5 meters every 8000 meters** so if the object is traveling 8000 m/s or 8 km/s it will never hit the earth.

## How can a projectile become a satellite?

A Satellite is a Projectile

**Once launched into orbit** the only force governing the motion of a satellite is the force of gravity. Newton was the first to theorize that a projectile launched with sufficient speed would actually orbit the earth.

## What factors affect how far a projectile will land?

**Factors affecting the flight path of a Projectile are:**

- Gravity.
- Air Resistance.
- Speed of Release.
- Angle of Release.
- Height of Release.
- Spin.

## What affects projectile motion?

**the downward force of gravity**. By definition a projectile has a single force that acts upon it – the force of gravity.

## Will satellites eventually fall?

**Satellites don’t fall from the sky because they are orbiting Earth**. Even when satellites are thousands of miles away Earth’s gravity still tugs on them. Gravity–combined with the satellite’s momentum from its launch into space–cause the satellite go into orbit above Earth instead of falling back down to the ground.

## What is the path of a projectile?

**its trajectory**.

## How can Brendan correct his diagram?

How can Brendan correct his diagram? **Change the Fg = Fc vector** so it is perpendicular to the v vector.

## What connection does Earth’s curvature have with the speed needed for a projectile to orbit Earth quizlet?

What connection does Earth’s curvature have with the speed needed for a projectile to orbit Earth? **The speed has to be great enough that the distance the projectile falls each second matches the Earth’s curvature.**

## When a projectile achieves escape speed from Earth it quizlet?

8 km/s. When a projectile achieves escape speed from Earth it does what? **It outruns the influence of Earth’s gravity but is never beyond it**.

## How fast must a projectile moving horizontally travel so that the curve it follows matches the curve of Earth?

an earth satellite. how fast must a projectile moving horizontally travel so that the curve it follows matches the curve of earth ? **about 8 km/s if it is close to earth**.

## When the Earth goes around the sun What is it called?

**a revolution**.

## What will possibly happen if the Earth will not revolve around the sun?

The escape velocity of the Earth is about 11 km/s. In other words anything on the Earth’s leading side would fly off into space continuing along the Earth’s orbital path around the sun. … Without the outward centripetal force to counteract the inward pull of gravity the Earth would **begin falling towards the sun**.

## Do satellites spin?

Most communications satellites are **dual spin** satellites. The rotor (plastered with solar arrays) rotates rather quickly for stability while the communications platform rotates but once per day.

## Is a projectile a free falling object?

A projectile is a **free-falling object**. A projectile experiences negligible or no air resistance. A projectile must be moving in the downward direction.

## What is projectile explain the factors affecting projectile trajectory?

Projectile: – An object thrown into space either horizontally or an acute angle under the action under gravity is called a projectile. There are **forces which act on a projectile** – gravitational force and air resistance. depends on the angle of release 0f projectile). …

## How do angles affect projectile motion?

**Higher launch angles have higher maximum height** The maximum height is determined by the initial vertical velocity. Since steeper launch angles have a larger vertical velocity component increasing the launch angle increases the maximum height.

## What angle will cause a projectile to travel the farthest?

**of 45 degrees**.

## What is the most important factor in projectile motion?

There are 3 factors that are most important in projectile motion: **The projection angle**. **The magnitude of projectile velocity**. **The height of the projection**.

## What is projectile motion in biomechanics?

**the motion of an object thrown or projected into the air subject to only the acceleration of gravity**. … The object or body is called a projectile and its path is called its trajectory.

## Will all space junk fall to Earth?

**an average of one cataloged piece of debris has fallen back to Earth each day for the past**50 years. Despite their size there has been no significant property damage from the debris.

## Can a satellite fall to Earth?

Getting rid of the smaller satellites in low orbits is simple. **The heat from the friction of the air burns up the satellite** as it falls toward Earth at thousands of miles per hour.

## What happens if you fall from space to Earth?

## What is nature of path of projectile?

The nature of path of projectile is **to follow the parabolic path**. And continue that till any external work is not done to change it. Hope it helps. Muxakara and 18 more users found this answer helpful.

## Why does a projectile follow the path it does?

projectile motion the motion of a falling object (projectile) after it is given an initial forward velocity. Air resistance and gravity are the only forces acting on a projectile. **The combination of an initial forward velocity and the downward vertical force of gravity** causes the ball to follow a curved path.

## How is the motion of a projectile analyzed?

**to break it into two motions one along the horizontal axis and the other along the vertical**.

## Which best explains why the object will not successfully orbit Earth?

Which best explains why the object will not successfully orbit Earth? **There is not enough air resistance to keep the object moving.** **There is not enough friction to keep the object moving**. … 1.2 × 106 m from Earth and Satellite Y is 1.9 × 105 m from Earth.

## Which object would be considered to be in free fall one that experiences?

An object moving upwards might not normally be considered to be falling but if it is subject to only the force of gravity it is said to be in free fall. **The Moon** is thus in free fall around the Earth though its orbital speed keeps it in very far orbit from the Earth’s surface.

## Which would cause the greatest increase in the acceleration?

Answer: A **decrease in the radius and an increase in the tangential speed**.

## Why is it important that the projectile in the preceding question be above Earth’s atmosphere?

A projectile falls beneath the straight-line path it would follow if there were no gravity. … Why is it important that the projectile in the previous question be above Earth’s atmosphere? **because the atmospheric friction experienced by the object would burn it**.

## Why does a person in free fall experience weightlessness while a person falling at terminal velocity does not?

A person in free fall experiences weightlessness because **there is no support force on him**. A person falling at terminal velocity does not experience weightlessness because of the support force provided by the air which equals mg .
