Projectile Motion and uniform circular motion

Front

What is centripetal acceleration?

Back

Centripetal acceleration is the acceleration that occurs in circular motion, directed towards the center of the circle.

Front

What direction does centripetal acceleration always point?

Back

Towards the center of the circle.

Front

If a bullet is shot horizontally and another is dropped from the same height, which hits the ground first?

Back

They hit at the same time.

Front

How does the time to hit the ground compare for an object projected horizontally from a cliff versus one that is dropped?

Back

They take the same amount of time to hit the ground.

Front

What is the formula to find the distance around a circle?

Back

2πr

Front

What is uniform circular motion?

Back

Uniform circular motion is the motion of an object traveling at a constant speed along a circular path.

Front

What is the net force direction on an object in uniform circular motion?

Back

The net force is directed toward the center of the circular path.

Front

What happens to the speed of an object in uniform circular motion?

Back

The speed remains constant, but the direction of the velocity changes.

Front

What is the relationship between the radius and the speed of an object in circular motion?

Back

For a given centripetal force, a larger radius results in a lower speed.

Front

What is the effect of gravity on a horizontally shot object compared to a dropped object?

Back

Both experience the same gravitational acceleration and fall at the same rate.
