Acceleration
|
change in velocity divided by time
|
|
|
Weight
|
the downward force exerted on objects due to gravity
|
|
|
Newton's first law of motion
|
every object maintains constant velocity unless acted on by an unbalanced force
|
|
|
Newton's second law of motion
|
The unbalanced force acting on an object equals the objects mass times acceleration
|
|
|
Newton's third law of motion
|
for every action there is an equal and opposite reaction force
|
|
|
which is not a factor in calculating momentum
|
acceleration
|
|
