- 18. Multiple Choice
Newton's FIRST law states:
an object in motion will remain in motion unless acted on by a net force
acceleration = net force ÷ mass
for every action, there is an equal but opposite reaction (forces act in pairs)
- 19. Multiple Choice
Newton's SECOND law states:
an object in motion will remain in motion unless acted on by a net force
acceleration = net force ÷ mass
for every action, there is an equal but opposite reaction (forces act in pairs)
- 20. Multiple Choice
Newton's THIRD law states:
an object in motion will remain in motion unless acted on by a net force
acceleration = net force ÷ mass
for every action, there is an equal but opposite reaction (forces act in pairs)
