Momentum

Momentum

• Momentum is a quantity possessed by masses in motion.

• It is a measure of how difficult it is to stop something that is moving.

• It is calculated by multiplying the mass of an object by its velocity.

momentum (kg m/s)=mass (kg) velocity (m/s)

p =mv

• Momentum is a vector quantity (a quantity that has both size and direction) and is measured in kilogram metres per second (kg m/s), provided that the mass in the equation is in kg and the velocity in m/s.

• The more mass an object has the more momentum it will have when moving.The momentum of an object also increases with speed.

Momentum and acceleration

• When a resultant force acts on an object it…
