Exploring Forces and Motion for Kids

What is a force in physics?

• A way to measure weight

• A kind of push or pull on an object

• A type of energy

• A measurement of speed

What happens when forces are balanced?

• The object moves faster

• The object changes direction

• The object stays still

• The object disappears

What causes an object to start moving?

• Gravity alone

• Unbalanced forces

• Being round in shape

• Balanced forces

What is motion?

• A measurement of weight

• A type of force

• A kind of energy

• A change in an object's position

What does velocity describe?

• The color of an object

• The shape of an object

• An object's speed and direction

• Weight of an object

According to Newton's first law, what will an object at rest do?

• Move randomly

• Stay at rest unless acted upon by an outside force

• Disappear

• Change color

What does Newton's second law of motion state?

• Acceleration is due to gravity only

• Force equals mass divided by acceleration

• Mass equals force plus acceleration

• Force equals mass times acceleration

How does mass affect the force needed to move an object?

• Mass has no effect on the force needed

• More mass means more force needed

• More mass means less force needed

• Less mass means more force needed

What does Newton's third law of motion explain?

• How gravity works

• For every action, there is an equal and opposite reaction

• Objects in motion stay in motion

• The relationship between mass and weight

Why did the dodgeball game help understand forces and motion?

• It showed how gravity affects objects

• It demonstrated the concepts of forces, motion, and Newton's laws in action

• It was just for fun, with no educational value

• It explained how to win at dodgeball
