d) inertia

This is often called the law of inertia.
a) first law of motion
b) third law of motion

d) fourth law of motion

This law states that for every action, there is an equal and opposite reaction.
a) third law of motion
b) first law of motion
c) second law of motion
d) fourth law of motion

This law implies that the force applied to an object is directly proportional to its acceleration.
a) second law of motion
b) third law of motion
c) first law of motion
d) fourth law of motion

This law says that the velocity of an object does not change unless the object is acted upon by an external force.
a) first law of motion
b) third law of motion
c) second law of motion
d) fourth law of motion

____________ is the tendency of an object to resist changes in its velocity.
a) inertia
b) speed
c) displacement
d) acceleration

When we see everyday objects in motion slowing down and becoming motionless, like a book sliding on a table, this is because of an unseen force known as __________.
a) friction
b) velocity
c) speed
d) displacement
