Question

Explain why you press against the seat when you take off fast at the beginning of the roller coaster ride. (Hint: relates to Newton’s first law)

Answer 1

Answer

When you are riding in a coaster car that is traveling at a constant speed, you only feel the downward force of gravity. But as the car speeds up or slows down, you feel pressed against your seat or the restraining bar. You feel this force because your inertia is separate from that of the coaster car.

Answer 2

For every action there is an equal and opposite reaction. This means that as you are pushed down, further and further in your seat, the seat is pushing back at you.
