Momentum is a commonly used term in sports. A team that has a lot of momentum is really on the move and is going to be hard to stop. Momentum is a physics term: Isaac Newton called momentum the “quantity of motion” It is also a measure of how much damage a moving object can cause.
Momentum can be defined as "mass in motion." All objects have mass; so if an object is moving, then it has momentum - it has its mass in motion. The amount of momentum that an object has is dependent upon two variables: how much stuff is moving and how fast the stuff is moving. Momentum depends upon the variables mass and velocity. In terms of an equation, the momentum of an object is equal to the mass of the object times the velocity of the object.
The symbol for mass is m. Mass is measured in kilograms (kg).
The symbol for velocity is v. Velocity is measured in meters per second (m/s).
The symbol for momentum is p. Momentum is measured in kilogram meters per second (kg m/s).
