gravity
The friction between the foot and the ground creates a force that opposes the motion of the skateboard, causing it to slow down. This friction converts the kinetic energy of the skateboard into thermal energy.
Inertia
Generally speaking for cars that have "disk brakes", friction slows the car. When the driver presses down on the brake pedal the brake calipers squeeze the brake pads against the brake rotor inside each car wheel causing the car to slow down by friction.
applying the brake
The force you apply is technically called applied force. It is transfered and used to move the brake pads together. At that point, the frictional force between the brake pads and the tire slows down the tire.
it change into potential energy beace it slows down
Friction is the force mainly responsible for slowing down a car. When the brake pads press against the brake rotors, friction is created, converting the kinetic energy of the car into heat energy, which ultimately slows down the vehicle.
The limiting frictional force is the force that slows down the tennis ball on the roller coaster.
When a driver applies the brake pedal, force is transmitted through the brake system to the brake pads which press against the brake rotors. The friction between the pads and rotors slows down the rotation of the wheels, converting the driver's effort into braking force that stops the vehicle.
Friction between the brake pads and the wheel rim or disc generates the force that slows down a bicycle when the brakes are applied. This friction converts the kinetic energy of the moving bicycle into heat, causing it to decelerate.
