2 watts of energy is expended
How you calculate the input force that you apply to bike pedals involves multiplying the force by the distance the object moves in the direction of the force. This is a part of the law of the lever.
If the object moves, then the energy is converted into the kinetic energy of the object. If it doesn't move, then no energy is imparted to it. If the force is applied by a human or animal, then the energy expended by the muscles to develop the force is radiated from the body as heat.
Work = (force) x (distance) = (2 x 1) = 2 newton-meters = 2 joulesPower = (work)/(time) = 2 joules / 1 second = 2 watts
Work is something that is done when a force moves an object over a distance.
Then one force is overcoming another force, and the object moves.
You would expend 2 watts of power when you exert a force of 1N that moves a book 2m in a time interval of 1s.

How you calculate the input force you apply to bike pedals involves the use of the law of the lever. In this case, the force must be multiplied by the distance that the object moves in the direction of the force.
Multiply the magnitude of the force component in the direction of motion by the distance through which it moves. The product is the work done by the force.
Work = (Force) x (Distance the object moves) x (cosine of the angle between force and motion)
Friction force
Any time an object moves, and especially if it changes its velocity, the laws of motion apply. For example, you can use it to calculate the desired force, if you know the acceleration and the mass. Or the other way - to calculate the acceleration, knowing the force and the mass.
It moves in the direction of the force acting on it.
Centrifical force.
its a force that moves by electric current
Because it moves force
