1
Q
Newton’s Three Laws of Motion
A
- Inertia
- Acceleration
- Action and Reaction
2
Q
acceleration is
A
force over mass
3
Q
Newton’s Law of Universal Gravitation
A
- the greater the mass, the greater the force of attraction
- the greater the distance, the less force
4
Q
amount of matter
A
mass
5
Q
pull of gravity
A
weight
6
Q
amount of space
A
volume
7
Q
compactness; how compact the particles are; amount of matter per unit volume
A
density
8
Q
True or False: the higher its density, the lower its volume
A
true
9
Q
True or False: the faster, the higher the kinetic energy
A
true
10
Q
True or False: the higher the position, the higher the potential energy
A
true
11
Q
change in momentum
A
impulse
impulse = force x time
12
Q
3 modes of heat transfer
A
- conduction (solids)
- convection (liquids and gases)
- radiation (vacuum)
13
Q
Law of Conservation of Momentum
A
total momentum is conserved before and after collision when there is no net external force
14
Q
rate of flow of charges
A
current
15
Q
opposition to the flow of charges
A
resistance
