1. Name newton's laws of motion
• ƒÞ Law of Inertia
• ƒÞ Law of Acceleration
• ƒÞ Law of Action-Reaction
2. What is the law of inertia
A body remains at rest or in constant linear velocity except when compelled by an external force to chang it stae
3. What is the law of acceleration?
The linear acceleration of a body is directly proportional to the force causing it, take place in the smae direction in whihc the force acts, and is inversly proportional to the mass of the body
4. What is the the law of action reaction
For every force there is an equal and opposite directed force.
5. what is (p) a symbol for
6. What is the Radius of gyration
distance between the axis of rotation and the center of mass
7. What is (I)
mass moment of inertia
8. what is the formula for Mass moment of inertia (I)
(I) = mass X p2
9. What is the formula for Force
Force = mass X acceleration
10. What is the formula for torque
Torque (moment) = I X angular acceleration
11. Momentum
Momentum = mass X velocity
12. Impulse
Impulse = force (T) X time
13. Work
Work = F (T) X displacement
14. Power
Power = work / time
15. Linear power
= F X d/t (or velocity)
16. Angular power
Angular power = T X angular velocity (ù)
