state the formula linking momentum, mass and velocity
momentum(kg m/s) = mass(kg) velocity(m/s)
State the principle of conservation
The total momentum before a collision = the total momentum after a collision
State the formula for the change of momentum
Change of momentum = Final momentum - Initial momentum.
formula for Force?
Force = Change in momentum Over Time
Newton’s third law
Whenever two objects interact, the forces they exert on each other are equal in magnitude and opposite in direction
newton’s third law in collisions
When two objects collide, both objects will react, generally causing one object to speed up (gain momentum) and the other object to slow down (lose momentum)
name 3 safety features in vehicles
Crumple zones
They are designed into the exterior of a building and are located at the front and back. they are designed to crush or crumple in a controlled way
Seat belts
These are designed to stop a passenger from colliding with the interior of a vehicle by keeping them fixed to their seat
airbags
They are deployed during a collision to act as a soft cushion and soften the impact
These absorb the energy from the impact help reduce the risk of injury
