SOL Review


Forces and motion

John goes over the top of a hill at a speed of 4m/s while on his bicycle. Four seconds later, his speed is 24m/s. What is John's acceleration?

  • 20 m/s sq.

  • 16 m/s sq.

  • 6 m/s sq.

  • 5 m/s sq.


Forces that are equal in size and opposite in direction are

Forces that are equal in size and opposite in direction are:

  • balanced forces

  • frictional forces

  • gravitational forces

  • net forces


Newton s first law of motion states that an object stays at rest unless a acts on it

Newton's first law of motion states that an object stays at rest unless a ____ acts on it.

  • balanced force

  • frictional force

  • gravitational force

  • net force


The rate of change of speed and or the change in direction is called

The rate of change of speed and/or the change in direction is called:

  • acceleration

  • average speed

  • gravity

  • velocity


The relationship among mass force and acceleration is explained by

The relationship among mass, force, and acceleration is explained by:

  • conservation of momentum

  • Newton's first law of motion

  • Newton's second law of motion

  • Newton's third law of motion


Which of the following objects has the greatest inertia

Which of the following objects has the greatest inertia?

  • baseball

  • bowling ball

  • pencil

  • table-tennis ball


As you climb a mountain you get farther from the center of the earth your weight will

As you climb a mountain, you get farther from the center of the earth.  Your weight will:

  • decrease

  • increase

  • remain the same


Forces and motion

A person, in a head-on car collision, who is not wearing a seat belt, continues to move forward at the original speed of the car because of:

  • friction

  • inertia

  • gravity

  • weight


The statement for every action there is an equal and opposite reaction is

The statement "for every action there is an equal and opposite reaction" is:

  • the law of conservation of momentum

  • Newton's first law of motion

  • Newton's second law of motion

  • Newton's third law of motion


The acceleration due to gravity is

The acceleration due to gravity is:

  • 98 m/s sq.

  • 9.8 m/s sq.

  • 9.8 m/s

  • 0.98 m/s

  • 150 Nm

  • 300 Nm

  • 302 Nm

  • 600 Nm
