The object with more mass will have more kinetic energy, assuming they are both moving at the same speed. Kinetic energy is directly proportional to an object's mass and velocity, so the object with greater mass will have a greater kinetic energy.
These include very large things, like planets, and very small ones, like atoms. The heavier a thing is, and the faster it moves, the more kinetic energy it has.
No, this statement is not true. Kinetic energy is determined by an object's mass and velocity, with faster objects typically having higher kinetic energy than slower objects of the same mass.
The large object moving at 25 mph would have more kinetic energy compared to the small object, assuming they have the same mass. Kinetic energy is dependent on both mass and velocity, so in this case, the larger object would have more kinetic energy due to its greater mass.
Molecules have more kinetic energy when they are moving. This energy is proportional to their speed and mass, making them collide with each other and their surroundings.
Kinetic energy and potential energy are forms of mechanical energy, where kinetic energy is associated with motion and potential energy is associated with position or stored energy. When an object with kinetic energy, like a moving car, comes to a stop, some of its kinetic energy is converted into thermal energy due to friction. This thermal energy is essentially the random kinetic energy of the particles that make up the object, resulting in an overall increase in temperature.
