Force is a vector quantity that describes the interaction between objects that causes a change in their motion, while conservation of energy is a principle stating that the total energy in a closed system remains constant over time. In other words, force is the cause of motion, while conservation of energy describes the effects of forces on a system's energy.

What is the connection between conservation of energy and centripetal force?
The conservation of energy principle states that the total energy of a system remains constant if no external forces act on it. In the case of circular motion, centripetal force provides the necessary inward acceleration to keep an object moving in a circular path. The work done by this force is supplied by the object's kinetic and potential energy, demonstrating the connection between conservation of energy and centripetal force.
How is friction different from the laws of conservation of energy?
Friction is a force that resists relative motion between two surfaces, leading to energy loss in the form of heat. The laws of conservation of energy state that energy cannot be created or destroyed, only transferred or transformed from one form to another. Friction causes energy to be dissipated, leading to a loss of mechanical energy in a system.
What is the difference between law of conservation of energy and conservation of momentum?
The law of conservation of energy states that energy cannot be created or destroyed, only transferred or transformed. Conservation of momentum, on the other hand, states that the total momentum of an isolated system remains constant unless acted upon by an external force. While energy accounts for the ability to do work, momentum accounts for the motion of an object.
What is the output force if the input force is 100n?
The output force will be 100N, assuming the system is ideal with no energy losses. This is based on the principle of conservation of energy, where input energy equals output energy in an ideal system.
What happens to the rate pf energy transfer between an object and its surroundings if the temperature difference between them is reduced?
If the temperature difference between an object and its surroundings is reduced, the rate of energy transfer between them will also decrease. This is because the driving force for heat transfer is smaller when the temperature difference is smaller.

Why the attraction is zero at the middle of a bar magnet?
Conservation of energy. Attraction is a force, force is zero at conservation of energy.The forces inside the bar magnet configure themselves spatially to conserve energy. The middle of the bar is also an inflection point for energy.

The output force will be 100N, assuming the system is ideal with no energy losses. This is based on the principle of conservation of energy, where input energy equals output energy in an ideal system.

Differentiate between potential difference and electro motive force?
Potential difference is the difference in electric potential energy between two points in a circuit. It is measured in volts and represents the work done in moving a unit charge across the points. Electro motive force (EMF) is the energy per unit charge supplied by a source, like a battery or generator, to move charge around a circuit. It is also measured in volts and represents the energy input provided by the source.
What is the difference between the input force and output force?
The difference between and input force and an output force is that an output force is force exerted by a machine, and an input force is force exerted on a machine.

What is the difference between gravitational potential energy and gravitational force?
Gravitational potential energy is the energy stored in an object due to its position in a gravitational field, while gravitational force is the force of attraction between two objects due to their masses. Gravitational potential energy is related to the height of an object, while gravitational force depends on the masses of the objects and the distance between them.
How do pulley systems illustrate the conservation of energy?
Pulley systems illustrate the conservation of energy by showing how the work input on one end is equal to the work output on the other end. As the force is spread out over a longer distance, the input work may stay constant, but the output work exceeds it. This demonstrates the principle of mechanical advantage, where there is a trade-off between force and distance to conserve energy in the system.
How do machines multiply force without multiplying work?
Work is the (force)*(distance)*(cosine of angle between force and distance). Therefore if you increase the force but the work remains the same either the distance has been reduced or the angle has changed.
