friction
Conservation of Energy explains why it speeds up. It also explains why it rolls, due to the frictional force creating a torque.
No it rolls, but not as fast as sions mum
As a car rolls down a hill, the motion and gravitational potential energy(GPE) will be equal when the kinetic energy is equal to the potential energy.
N^egative acceleration = X4 =
Gravitational force.
you have to put your handbrake on and then it wont roll down the hill
No. A rock rolls down a hill due to the force of gravity, also known as gravitic force.
Yes she rolls down a hill, hits her head and dies.
When a mountain of snow comes clashing down and rolls down a hill and keeps getting bigger and bigger.
Potential energy to kinetic energy
If you are on a skateboard going x miles per hour, and you come across a downhill slope, your velocity will increase as you go down the hill.
