Force in Motion Reading

What is a force in science?

• A push or a pull

• A type of energy

• A form of matter

• A chemical reaction

What unit is used to describe the size of a force?

• Joule

• Watt

• Newton

• Pascal

What happens when the net force on an object is 0 N?

• The object accelerates

• The object changes direction

• The object does not move

• The object increases speed

How do you determine the net force when two forces act in the same direction?

• Subtract the smaller force from the larger force

• Add the two forces together

• Multiply the two forces

• Divide the larger force by the smaller force

What is the result of unbalanced forces acting on an object?

• The object remains stationary

• The object changes its motion

• The object decreases in size

• The object becomes heavier

What are the two properties that all forces have?

• Mass and volume

• Direction and size

• Speed and velocity

• Energy and power

What happens to a soccer ball when it is kicked?

• It remains stationary

• It moves due to an unbalanced force

• It decreases in size

• It becomes heavier

Explain If there are many forces acting on an object, how can the net force be 0?
