- Module 1 - Newton's laws and momentum
- Newtons Laws of Momentum
- Newton's First Law
- A force is necessary to change the state of rest or uniform motion in a straight line of a body.

- Newton's Second Law
- The rate of change of the momentum of an object is directly proportional to the net force acting upon it.
- F=ma is a special case of Newton's Second Law
- Occurs when mass is constant

- Newton's Third Law
- When body A exerts a force on body B, then body B exerts on body A that is equal, opposite in direction and of the same type.

- Newton's First Law
- Linear Momentum
- The product of mass and velocity and is defined as a vector.
- p=mv

- The product of mass and velocity and is defined as a vector.
- Force is equal to the change in momentum over the change in time.
- F=dp/dt
- F=ma is a special case of Newton's Second Law
- Occurs when mass is constant

- F=ma is a special case of Newton's Second Law

- F=dp/dt
- The area under a force/time graph is equal to the impulse.
- The change of momentum in a body.
- I=m(v-u)

- The change of momentum in a body.
- Impulse
- The change of momentum in a body.
- I=m(v-u)

- The change of momentum in a body.
- Collisions
- Perfectly Elastic Collision
- A collision which no momentum or kinetic energy is lost.

- Inelastic Collision
- A collision where momentum is conserved but kinetic energy is not.

- Whilst the momentum of a system is always conserved in the interaction between bodies,some change in kinetic energy usually occurs.
