Unit 7: Forces Quiz - Grade 3

What is a force?

• A push or pull

• A form of matter

• A type of energy

• A sound wave

Give an example of a push.

• Pushing a door to open it.

• Pulling a door to open it

• Turning on a light switch

• Sitting down in a chair

Give an example of a pull.

• Pushing a heavy object

• Tug of war

• Jumping off a cliff

• Swimming against a current

Explain the difference between a push and a pull.

• A push and a pull have no difference in their effect on an object.

• A push moves an object away, while a pull moves an object towards the source of the force.

• A push and a pull both move an object towards the source of the force.

• A push and a pull both move an object away from the source of the force.

How do forces affect the motion of objects?

• Forces can make objects disappear

• Forces can change the speed, direction, or shape of an object's motion.

• Forces only affect the color of an object

• Forces have no effect on the motion of objects

What is the definition of force?

• A type of energy

• The color of an object

• A push or pull upon an object resulting from the object's interaction with another object.

• The speed of an object

What is the relationship between mass and weight?

• Mass and weight are the same thing

• Weight is the force exerted on an object due to gravity, while mass is the amount of matter in an object.

• Weight is the amount of matter in an object, while mass is the force exerted on an object due to gravity

• Mass is the force exerted on an object due to gravity, while weight is the amount of matter in an object

Explain the concept of mass.

• Mass is a measure of the amount of matter in an object.

• Mass is a measure of the speed of an object.

• Mass is a measure of the volume of an object.

• Mass is a measure of the force exerted by an object.

Explain the concept of weight.

• Weight is the amount of air in an object.

• Weight is the speed at which an object falls.

• Weight is the color of an object.

• Weight is the force exerted on an object due to gravity.

In which units can we measure force?

• newton

• meter

• kilogram

• gram
