Acceleration
to figure out the force of something, you need to times the mass by the acceleration
to find out mass, you need to divide force by acceleration
-
to find out acceleration, you need to divide the change in speed by time.
speed
-
Speed is stated as a length per unit of time. For example a speed could be 70 miles per hour, while another speed could be 45 metres per second.
Calculate speed using the speed equation - speed = distance divided by time. The speed equation can be rearranged to find distance travelled and time taken.
Momentum
For example an elephant has no momentum when it is standing still. When it begins to walk it will have momentum in the same direction as t is travelling. The faster the elephant walks the larger the momentum will be
Momentum is the product of mass and velocity. momentum is also a vector quality - this means it has both a magnitude and a direction.

Drag Forces and friction
Drag Forces
Drag forces are like friction types, eg, water, air and other elemental resistances reduce speed to varying degrees
Friction
Friction is where particles are in the way of others, the blocked particles use some energy to either move past or push the blocking particle out of the way
