How does gravity and friction affect roller coasters?
How does gravity and friction affect roller coasters? The coaster tracks serve to channel this force — they control the way the coaster cars fall. If the tracks slope down, gravity pulls the front of the car toward the ground, so it accelerates. If the tracks tilt up, gravity applies a downward force on the back of the coaster, so it decelerates.
What force makes the roller coaster lose energy?
Real roller coasters lose energy to friction and air resistance, which limits the energy they have available to travel the rest of the track. Unbalanced forces cause the cart to accelerate according to Newton's second law, speeding up on the downhills and slowing down on the uphills.
How would air resistance and gravity affect a roller coaster?
Air resistance affects a roller coaster as it is in the air, and it provides a force that is countering the movement of the cart. This force can be big, such as when there is heavy wind, or it can be small, when there is no wind. However, it always has an effect on the speed of the cart.
How is gravity friction and inertia used in roller coasters?
Friction against the track and air resistance act against inertia, so each subsequent hill is lower. Early coasters were very slow, so coasters were engineered for the illusion of speed through low hanging ceilings and deliberately swaying tracks.
What force causes a roller coaster to slow?
As the roller coaster slows down (deceleration) due to friction between the wheels and the track or air rushing by, the forces a rider feels ease off.
