Projectile Motion Test Review

Front

What is projectile motion?

Back

Projectile motion is the motion of an object thrown into the air, subject to the force of gravity, following a curved path called a trajectory.

Front

What are the two components of projectile motion?

Back

The two components are horizontal motion (constant velocity) and vertical motion (accelerated due to gravity).

Front

What is the acceleration due to gravity?

Back

The acceleration due to gravity is approximately 9.81 m/s² downward.

Front

If a ball is thrown straight up and takes 4 seconds to reach its peak, how long will it take to return to the original position?

Back

4 seconds.

Front

What is the horizontal velocity of a projectile dropped from a moving object?

Back

It is the same as the velocity of the moving object.

Front

Which Lemming will hit the ground farther from the base of the cliff if Lemming A runs off at 2 m/s and Lemming B at 1 m/s?

Back

Lemming A will hit the ground farther.

Front

What is the sum of multiple vectors called?

Back

Resultant Vector.

Front

What defines a vector?

Back

A vector has both direction and magnitude.

Front

What is a scalar quantity?

Back

A scalar quantity has only magnitude and no direction.

Front

How does air resistance affect projectile motion?

Back

Air resistance opposes the motion of the projectile, reducing its range and altering its trajectory.
