How can Newton's laws explain amusement park rides?
How can Newton's laws explain amusement park rides? Newton's first law tells us that an object at rest stays at rest (without outside interference), so a motor must first push the amusement park ride up into the air. Then gravity pulls the ride back down. The ride has inertia, which keeps it in motion. The ride moves up and down with the help of inertia and gravity.
What is an example of inertia on a roller coaster?
Roller coasters are ruled by the Law of Inertia. Since an object at rest, stays at rest, at the beginning of the ride a stationary roller coaster is at rest and will need to be pushed or pulled along to get it started.
What is the force applied to a roller coaster?
A roller coaster is a machine that uses gravity and inertia to send a train of cars along a winding track. The combination of gravity and inertia, along with g-forces and centripetal acceleration give the body certain sensations as the coaster moves up, down, and around the track.
What forces cause the roller coaster to speed up and slow down?
The force of gravity pulling a roller coaster down hill causes the roller coaster to go faster and faster, it is accelerating. The force of gravity causes a roller coaster to go slower and slower when it climbs a hill, the roller coaster is decelerating or going slower.
How do roller coasters obey the laws of physics?
If the tracks tilt up, gravity applies a downward force on the back of the coaster, so it decelerates. Since an object in motion tends to stay in motion (Newton's first law of motion), the coaster car will maintain a forward velocity even when it is moving up the track, opposite the force of gravity.
