Question

Select forms of kinetic energy

A pendulum at its highest point
Running
Heat
Molecular motion

Answer 1

The forms of kinetic energy from your list are:

1. **Running** - This is a direct example of kinetic energy, as it involves the movement of a person or animal.
2. **Molecular motion** - This also constitutes kinetic energy, as the movement of molecules in a substance contributes to its thermal energy.

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

- **A pendulum at its highest point** has maximum potential energy and minimal kinetic energy at that moment.
- **Heat** refers to thermal energy, which is related to the motion of molecules, but it is not a direct form of kinetic energy itself.

So the correct selections are **Running** and **Molecular motion**.
