1
Q
describe newtons first law
A
- law of inertia
- a body will continue in a state of constant velocity unti lcompelled to change by an external force
2
Q
describe newtons second law
A
- law of acceleration
- a body will accelerate proportionally to the force applied
- in the same direction
3
Q
decribe newtons third law
A
- law of reaction
- every action has an equal and opposite reaction
4
Q
give the force equation
A
force = mass x acceleration
5
Q
