Question

which of the following statements about forces is true?
matter is a force.
forces act alone.
a force is a push or a pull.

Explanation:

• Matter is a substance with mass and volume, not a force, so the first statement is false.
• Forces always act between two objects; they cannot act alone, so the second statement is false.
• By definition, a force is described as a push or pull on an object, so this statement is true.

Answer:

A force is a push or a pull.
