Final answer:
In physics, force refers to a push or a pull that one object exerts on another. It can cause an object to change its speed, direction, or shape. Force can occur even when objects are not touching each other.
Step-by-step explanation:
In physics, when scientists use the term force, they are referring to a push or a pull that one object exerts on another. Force can cause an object to change its speed, direction, or shape. It is measured in units called Newtons (N).
For example, when you push a door to open it, you apply a force. When you throw a ball, you exert a force on it. Even the force of gravity pulling objects toward the Earth is a type of force.
It is important to note that force can occur even when objects are not touching each other. This is known as a non-contact force, like the force of magnetism.
