Forces and Motion Quiz

What is the essential question about forces in this lesson?

• How do forces affect the motion of objects?

• What is the color of force?

• Who discovered gravity?

• How do objects stay still?

What unit is used to measure the strength of a force?

• Newtons (N)

• Meters (m)

• Seconds (s)

• Kilograms (kg)

What is the net force when forces are balanced?

• Zero

• One

• Ten

• Infinite

Do balanced forces cause a change in motion?

• No

• Yes

• Sometimes

• Only if the object is moving

If the net force does NOT equal zero, what type of forces are acting?

• Unbalanced forces

• Balanced forces

• Magnetic forces

• Gravitational forces

Which of the following is true about unbalanced forces?

• They do cause a change in motion

• They are always equal in size

• The net force is always zero

• They never affect objects

Which scenario best describes balanced forces?

• Two people pushing a box with equal force in opposite directions and the box does not move

• One person pushing a box and it moves

• A dog pulling a shoe and the shoe moves

• A ball rolling down a hill

When Forces are Balanced it is said that there is?

• No change in motion

• speeding up of the object

• slowing down of the object

• The object changes direction

What does the net force determine?

• Whether an object will change its motion

• The color of an object

• The temperature of an object

• The size of an object

If gravity pulls down and the floor pushes up with equal force, what is the result?

• No movement

• The object floats

• The object sinks

• The object spins
