Newton's 3rd Law
|
*the third law of motion deals with pairs of objects.
*This is because all forces come in pairs. |
|
|
Newton's 3rd Law states
|
*for every action force, there is a reaction force equal in strength and opposite in direction.
|
|
|
Momentum
|
*the momentum of a moving object is its mass multiplied by its velocity.
*measures a moving objects resistance to changes in its motion. |
|
|
calculating momentum
|
momentum (p) is calculated with velocity instead of speed because the direction of momentum is always important.
*momentum to the right is always positive and to the left is negative. |
|
|
Impulse
|
*a change in momentum created by a force exerted over time.
|
|
|
Impulse formula
|
Ft= mv2 - mv1
**refer to page 62 in the book |
