friction
Yes, as the bicycle rolls down the hill, there is still some friction present between the wheels and the surface of the hill. This friction helps to slow down the bicycle's descent and eventually bring it to a stop.
A ball slowing down as it rolls up a hill is an example of kinetic energy being converted into potential energy. As the ball moves uphill, it loses kinetic energy which is converted into gravitational potential energy due to its increased height. This conversion causes the ball to slow down.
Friction acts in the opposite direction to the direction of the sliding motion. In the case of an object rolling down a hill, the friction force would act against the direction of the object's motion, trying to slow it down or prevent it from sliding further.
if there is friction on the hill it will slow you down
No. Speed and force cause a bowling ball to roll down a lane. Friction may cause a bowling ball to change course on a lane though, and also slow it down.
when you are skiing down a hill and you want to slow down
Yes, gravity can slow down an object if it is acting in the opposite direction of the object's motion. For example, if an object is thrown upwards, gravity will work against the object, slowing it down until it eventually stops and falls back to the ground.
it depends on the mass of an object
=normally objects slow down because of the friction. this means that the surface area is in contact with the air particles so that will slow the object down.==or they put the breaks on .=
You can make an object slow down by applying a force in the opposite direction of its motion, such as friction or air resistance. Another way is to reduce the energy or speed of the object by transferring some of it to another object through collision or contact.
No, force is not always needed to slow down an object. In cases where there is friction or air resistance, these forces can naturally slow down an object without the need for external force. For example, a ball rolling on a table will slow down due to the friction between the ball and the table surface.
The skier will gain momentum as they travel down the hill but once the hill flattens out they will eventually slow down due to friction
