Question

which statement is true of forces? forces have strength and direction. forces are measured in miles per hour. forces do not have a specific direction.

Explanation:

• For the first option: In physics (a subfield of Natural Science), a force is a vector quantity, which means it has both magnitude (strength) and direction. This is a fundamental concept about forces.
• For the second option: Miles per hour is a unit of speed or velocity, not force. The unit of force is the newton (in SI units) or pounds (in imperial units). So this statement is false.
• For the third option: As forces are vector quantities, they must have a specific direction. So this statement is false.

Answer:

Forces have strength and direction.
