Newton's Laws
- Newton's First Law
- An object at rest will remain at rest unless
acted on by an unbalanced force. An object
in motion continues in motion with the
same speed and in the same direction
unless acted upon by an unbalanced force.
- Law of Inertia
- Inertia-measure of how hard it is to change motion of a mass
- Newton's Second Law
- Acceleration is produced when a force acts
on a mass. The greater the mass (of the
object being accelerated) the greater the
amount of force needed (to accelerate the
object).
- Force=Mass x Acceleration
- Air resistance caused by collision
between air particles and object
surface
- Newton's Third Law
- For every action there is an equal and
opposite re-action.
- Friction acts in opposite direction of motion
