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.

- balanced forces
- frictional forces
- gravitational forces
- net forces

- balanced force
- frictional force
- gravitational force
- net force

- acceleration
- average speed
- gravity
- velocity

- conservation of momentum
- Newton's first law of motion

- 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 law of conservation of momentum
- Newton's first law of motion
- Newton's second law of motion
- Newton's third law of motion

- 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
