Momentum
Momentum Momentum measures how hard it is to stop a moving object
or how hard it is to get it started moving. Momentum
depends on how much mass an object has and how fast it is
going (velocity).
General
Rules
1.The more mass an object has, the harder it is to
stop it or get it to change direction.
2. The faster an object is going, the harder it is to
get it to stop or change direction.
3. The more mass an object has, the harder it is to
get it to start moving.
4. The faster an object is moving, the harder it is to
get it to move even faster.
Momentum Momentum is calculated by multiplying the mass in
Equation
kilograms by the velocity in meters per second.
momentum = mass x velocity
Example
1. A 1000kg motorcycle is going 10m/s. What is its
momentum?
momentum = m x v
= 1000kg x 10m/s
= 10,000kg m/s
2. Find the momentum for a 500kg motorcycle.
momentum = m x v
= 500kg x 10m/s
= 5000kg m/s
3. Find momentum for the motorcycle in the first problem
going only 5m/s.
momentum = m x v
= 1000kg x 5m/s
= 5000kg m/s
