For example if I punch an object and it doesn't move, am I giving it energy, if so after doing that billions of times wouldn't it gain mass because e=mc2.
You are not. The Earth (or whatever prevents the object from moving) pushes against the object in the opposite direction, and the energy gained by the object is 0. If you take deformations into account, you could heat it a tiny bit, but that is not related to the motion of the whole object.For example if I punch an object and it doesn't move, am I giving it energy
Depends I guess. If you are hammering iron to make a sword you transfer quite a lot of energy into unmovable object.Berney123 said:For example if I punch an object and it doesn't move, am I giving it energy, if so after doing that billions of times wouldn't it gain mass because e=mc2.
No, energy can only be transferred from one object to another if there is motion involved. This is because energy is defined as the ability to do work, and work is only done when a force acts on an object and causes it to move.
Any type of motion can transfer energy, including linear motion, rotational motion, and vibrational motion. For example, when a car accelerates, its engine transfers energy to the wheels through linear motion, while a wind turbine converts rotational motion into electrical energy.
Yes, there is a limit to how much energy can be transferred through motion. This limit is called the maximum kinetic energy, which is dependent on the mass and speed of the object. Once the maximum kinetic energy is reached, any additional energy will be dissipated as heat or sound.
Yes, energy can be transferred through motion in a vacuum. In fact, motion in a vacuum allows for the most efficient transfer of energy, as there is no air resistance or friction to slow down the object. This is why objects in space can travel at high speeds without losing much energy.
Yes, there are other ways to transfer energy besides motion. Energy can also be transferred through heat, light, sound, and electric or magnetic fields. In fact, energy is constantly being transferred and transformed from one form to another in various natural processes and human-made systems.
