Grade 12 Physics Concepts: Types of Collisions
Elastic Collisions In an elastic collision, the total kinetic energy in the system is the same before and after the collision. Losses to...
Grade 12 Physics Applications: Safety Features Relating to Impulse
Seat Belts Seat belts stop you tumbling around inside the car if there is a collision. However, they are designed to stretch a bit in a...
Grade 12 Physics Concepts: Impulse
The formula for impulse is written as FΔt=Δp where F is force acting on an object, Δt is time the force is acting on an object and Δp is...
Grade 12 Physics Concepts: Momentum
The formula for momentum is written as p=mΔv, where p=momentum, m=mass and Δv=change in velocity. Both velocty and momentum are vector...
