Free Fall & Projectile Motion

Front

What is the variable letter for range or horizontal displacement in projectile motion?

Back

d_x

Front

Which diagram best describes the motion of a free-falling object that is dropped from rest?

Back

Diagram B

Front

What is the vertical acceleration of a projectile in free fall, assuming no air resistance?

Back

-10 m/s²

Front

What is the initial vertical speed of a marble rolling off a 1 m high table at 3 m/s?

Back

0 m/s

Front

How do the initial vertical velocity (Viy) and final vertical velocity (Vfy) compare when a ball is thrown up and caught at the same height?

Back

Viy and Vfy are the same in magnitude, but different in direction.

Front

Define free fall.

Back

Free fall is the motion of an object under the influence of gravitational force only.

Front

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

Back

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

Front

What is the effect of air resistance on projectile motion?

Back

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

Front

What is the trajectory of a projectile?

Back

The trajectory of a projectile is the path it follows through space, typically a parabolic shape.

Front

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

Back

Horizontal motion is uniform (constant velocity), while vertical motion is influenced by gravity (accelerated motion).
