- 1. Multiple Choice
Newton's First Law States........
Objects at rest tend to stay at rest unless acted on by an outside force.
Objects accelerate often and it is difficult to know when or how they will accelerate.
Objects in motion tend to stay in motion unless acted on by an outside force.
Both A & C
- 2. Multiple Choice
What is inertia?
An object that is accelerating
Gravitational force
An objects tendency to stay at rest or in motion
An unbalanced force
- 3. Multiple Choice
Inertia depends on __________.
Weight
none of these
Mass
Acceleration
- 4. Multiple Choice
What formula is used to calculate force?
Acceleration = Force x Mass
Force = Mass x Acceleration
Work = Force x Distance
Mass = Force + Acceleration
