Question

Select forms of kinetic energy
Molecular motion
A pendulum at its highest point
Heat
Running

Answer 1

The forms of kinetic energy from your list are:

1. **Molecular motion** - This is related to the kinetic energy of particles in gases, liquids, and solids, which is a form of kinetic energy.
2. **Running** - When a person or object is in motion, they possess kinetic energy due to their velocity.

The other options, "A pendulum at its highest point" and "Heat," do not represent forms of kinetic energy:

- **A pendulum at its highest point** has maximum potential energy and minimum kinetic energy since it momentarily comes to rest at that point.
- **Heat** is a form of energy associated with the motion of particles but is not a direct form of kinetic energy; it is often associated with the thermal energy of a system.

So, the correct forms of kinetic energy are **Molecular motion** and **Running**.
