Front

Does the mass of an object affect the rate at which it falls in a vacuum?

Back

No, all objects fall at the same rate regardless of mass.

What is the relationship between vertical velocity and time for an object in free fall?

Back

The vertical velocity increases as time increases.

Front

What is the formula for calculating the horizontal range of a projectile?

Back

Range = (initial velocity * time) * cos(θ), where θ is the launch angle.

Front

What is the difference between horizontal and vertical motion in projectile motion?

Back

Horizontal motion is constant velocity, while vertical motion is affected by gravity.

Front

What is the term for the horizontal component of velocity in projectile motion?

Back

vₓ (horizontal velocity).

Front

How does the height from which a projectile is launched affect its horizontal range?

Back

A greater height increases the time of flight, resulting in a greater horizontal range.

Front

What is the effect of air resistance on projectile motion?

Back

Air resistance decreases the range and alters the trajectory of the projectile.

Front

What is the trajectory of a projectile?

Back

The path followed by a projectile, typically a parabolic shape.
