Newton’s Laws of Motion Quiz

Once an applied force causes an object to start moving, the object keeps moving because

• the force continues to be applied to it

• no other force is acting on it

• it has inertia

• none of the above

Inertia causes a stationary object to

• start moving

• remain stationary

• have an increase in velocity

• change its speed or direction

An object with greater mass has greater inertia.

• True

• False

Balanced forces are needed to change an object’s motion.

• True

• False
