change in position / change in time
3. change in position =
final position - original position
4. change in time =
final time - original time
5. velocity is concerned with the..
distance covered
6. speed is concerned with the..
distance covered
7. average speed =
total distance / change in time
8. average acceleration =
change in velocity / change in time
9. Newton's Law states that a body at rest..
will tend to remain at rest; while a body in motion will tend to remain in motion
10. Newton's second law of mechanics states that Force =
mass X acceleration
11. normal force is
the perpendicular force exerted on an object that is restingĀ on some other surface
12. Newton's third law of mechanics. for every force...
there is an equal and opposite force
13. what type of surfaces tend to create less friction
flatter and harder
14. work =
Fd ; F is the magnitude of the force exerted and d is the displacement of the object on which the force is exerted.
