1D Kinematics Test Review

An object is thrown vertically upward. Which one of the following is true?

• It's velocity changes non-uniformly

• The maximum height is independent of the initial velocity

• The travel time upward is slightly greater than the travel time downward

• The speed on returning to its starting point is the same as the initial speed

A dropped object in free fall...

• Fall 9.8 m each second

• Falls 9.8 m in the first second

• Has an increase in speed of 9.8 m/s each second

• Has an increase in acceleration of 9.8 m/s each second

Why do objects fall at different rates on Earth?

• The mass of the object affects the rate of fall

• The acceleration due to gravity is different in each object

• The air resistance on some objects slows the rate of fall

• Unable to determine
