Kinematics 1D Practice Test

An object is released from rest near a planet’s surface. A graph of the acceleration as a function of time for the object is shown for the 4 s

2 s?

• −20 m

• −10 m

• 10 m

• 20 m

A ball is thrown upward with a speed of 20 m/s. What is the time to max height?

• 1 seconds

• 2 seconds

• 4 seconds

An object is sliding to the right along a straight line on a horizontal surface. The graph shows the object’s velocity as a function of time. What is the object’s displacement during the time depicted in the graph?

• 0m

• 2m

• 3m

• 8m

An object is thrown with an initial speed v near the surface of Earth. Assume that air resistance is negligible and the gravitational field is constant.

If the object is thrown vertically upward, the direction and magnitude of its acceleration while it is in the air is

• upward and decreasing

• upward and constant

• downward and decreasing

• downward and constant
