Projectile Motion Review

Front

What happens to the vertical velocity of a projectile as it falls?

Back

It is increasing as the projectile falls.

Front

If Lemming A runs off a cliff at 2 m/s and Lemming B at 1 m/s, which will land farther from the cliff?

Back

Lemming A will hit the ground farther from the base of the cliff.

Front

Which of the following is NOT a projectile? A cannonball rolling down a slope, a cannonball fired towards a castle, a cannonball fired straight outward, or a cannonball after rolling off a cliff?

Back

A cannonball rolling down a slope.

Front

What shape does the path of a projectile follow?

Back

Parabolic.

Front

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

Back

They both hit at the same time.

Front

Define 'projectile motion'.

Back

Projectile motion is the motion of an object thrown into the air with an initial velocity, subject to the force of gravity.

Front

What are the two components of projectile motion?

Back

Horizontal and vertical components.

Front

How does air resistance affect projectile motion?

Back

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

Front

What is the acceleration of a projectile in the vertical direction?

Back

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

Front

What is the formula for the range of a projectile launched at an angle?

Back

Range = (v^2 * sin(2θ)) / g, where v is the initial velocity, θ is the launch angle, and g is the acceleration due to gravity.
