Newton's Laws Of Motion

What is the unit of measurement for force?

• Kilograms

• Meters per second squared

• Newtons

• Joules

Can more than one force act on an object at the same time?

• Yes

• No

• Only in a vacuum

• Only on Earth

According to the diagram, what is the net force acting on the object and in which direction?

• 3 N to the right

• 7 N to the left

• 3 N to the left

• 1 N to the right

What are balanced forces?

• Forces that cause a change in motion.

• Forces that are unequal in size and same in direction.

• Forces that are equal in size and opposite in direction.

• Forces that increase the net force on an object.

What is the net force on an object when the forces are balanced?

• Equal to the strongest acting force.

• Cannot be determined.

• Greater than zero.

• Zero.

Do balanced forces cause a change in motion of an object?

• Yes, they always cause a change in motion.

• Yes, but only if the object is already moving.

• No, they do not cause a change in motion.

• No, unless acted upon by another unbalanced force.

What are unbalanced forces?

• Forces that are equal in size and opposite in direction.

• Forces that are not equal in size and opposite in direction.

• Forces that cancel each other out completely.

• Forces that are equal in size and same in direction.

What is Newton's 1st Law of Motion also known as?

• Law of Universal Gravitation

• Law of Acceleration

• Law of Inertia

• Law of Interaction

According to Newton's 1st Law of Motion, what will an object at rest do unless a net force acts on it?

• It will start moving at a constant velocity.

• It will stay at rest.

• It will accelerate.

• It will move in a circular path.

What will an object in motion continue to do according to Newton's 1st Law of Motion?

• It will slow down and stop.

• It will change direction.

• It will stay in motion at a constant velocity.

• It will increase its velocity.
