Understanding Free Falling Objects

What is the primary force acting on a free falling object?

• Magnetism

• Gravity

• Air resistance

• Friction

In the example problem, what is the height from which the ball is dropped?

• 50 meters

• 73 meters

• 100 meters

• 120 meters

Which kinematic variable is not mentioned in the example problem?

• Displacement

• Time

• Final velocity

• Initial velocity

Which kinematic equation is used to solve the problem?

• d = vit + 0.5at^2

• vf^2 = vi^2 + 2ad

• vf = vi + at

• d = (vf + vi)/2 * t

What is the final velocity of the ball when it hits the ground?

• 20.0 m/s

• 9.8 m/s

• 50.0 m/s

• 37.8 m/s
