Projectile Motion

Front

What is projectile motion?

Back

Projectile motion is the motion of an object that is thrown into the air and is subject to the force of gravity. It follows a curved path called a trajectory.

Front

What are the two components of projectile motion?

Back

The two components of projectile motion are the horizontal component and the vertical component.

Front

How does the horizontal velocity of a projectile relate to the velocity of the object it is dropped from?

Back

The horizontal velocity of a projectile dropped from a moving object is the same as the velocity of the moving object.

Front

What happens to the vertical component of a projectile's motion?

Back

The vertical component changes due to the acceleration of gravity, while the horizontal component remains constant.

Front

If two objects are dropped from the same height, how do their times to hit the ground compare?

Back

If a dropped ball and a ball launched with horizontal velocity start at the same height, they both hit the ground at the same time.

Front

What is the effect of air resistance on projectile motion?

Back

Air resistance can slow down the projectile and alter its trajectory, but in ideal conditions (without air resistance), the motion can be predicted using basic physics.

Front

What is the significance of the peak in projectile motion?

Back

The peak is the highest point in the trajectory where the vertical velocity is zero before the object starts descending.

Front

How long does it take for a ball thrown straight up to return to its original position?

Back

The time taken to return to the original position is equal to the time taken to reach the peak.

Front

If a ball takes 4 seconds to reach the peak, how long will it take to return?

Back

It will take 4 seconds to return to the original position.

Front

What is the relationship between the magnitude and direction of velocity at different points in a vertical throw?

Back

The magnitude of velocity is the same at equal heights during ascent and descent, but the direction is opposite.
