What does Newton's First Law state?

• Force equals mass times acceleration

• Every body continues in its state of rest or uniform motion unless acted upon

• For every action, there is an equal and opposite reaction

• Momentum is conserved in a closed system

What is force defined as?

• A change in velocity

What are like parallel forces?

• Forces of unequal magnitude only

• Forces acting in opposite directions

• Forces acting along the same direction

• Forces acting at right angles

What is the resultant force?

• The sum of all forces acting on a body

• The force that stops a moving body

• The force that changes direction

• The force that acts in one direction only
