Chapter 8 Flashcards
1
Q
Newton’s first law or law of inertia
A
An object at rest will remain at rest unless acted upon by a nonzero net force. An object moving at a constant velocity will continue moving at a constant velocity unless acted upon by a nonzero net force
2
Q
What is inertia
A
Resistance to change in motion
3
Q
Newton’s second law
A
An object’s acceleration depends on its mass and the net force acting on it
4
Q
Formula for acceleration
A
Acceleration= Net force divided by Mass
5
Q
Two factors that affect gravity
A
Mass and distance
6
Q
Formula for net force
A
Mass times acceleration
7
Q
Newton’s third law of motion
A
For every action there is an equal but opposite reaction
8
Q
Formula for momentum
A
Momentum= Mass • Velocity
