Forces and Motion SOL Review
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: • 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. • balanced force • frictional force • gravitational force • net force
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: • 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? • baseball • bowling ball • pencil • table-tennis ball
As you climb a mountain, you get farther from the center of the earth. Your weight will: • decrease • increase • remain the same
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 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: • 98 m/s sq. • 9.8 m/s sq. • 9.8 m/s • 0.98 m/s
A 300N force is used to move an object 2M. The amount of work equals: • 150 Nm • 300 Nm • 302 Nm • 600 Nm
Two simple machines that are part of a bicycle are: • A wheel an axle and a screw • An inclined plane and a lever • An inclined plane and a wedge • A screw and an inclined plane
