Different strengths of forces can be modeled using

• arrows of different lengths
• scales that measure different forces.
• a table of different numerical values.
• a graph of different numerical values.

Two pendulums colliding are an example of

• a force pair where both forces can be seen.
• a force pair where only one force can be seen.
• a force pair where the forces cancel each other out.
• a force pair where the strength of forces is doubled.

Newton’s third law of motion states that when an object exerts a force on a second object, the second object

• exerts a weaker force in the opposite direction.
• exerts a stronger force in the opposite direction.
• exerts a force with equal strength in the same direction.
• exerts a force with equal strength in the opposite direction.
