Question

q.2. use the words in the box to complete sentences about newtons first law of motion.

• unbalanced force • in motion
• at rest • balanced force

a) an object at rest tends to stay
b) an object in motion tends to stay
c) an object acted upon by stays at rest.
d) an object acted upon by changes speed and direction.

Explanation:

Newton's first law states an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force. Balanced forces result in no change in motion for an object at rest. Unbalanced forces cause a change in speed and direction of an object's motion.

Answer:

a) at rest
b) in motion
c) balanced force
d) unbalanced force
