4G SC- Energy In Motion Practice Test

What is energy?

• A push or pull on an object

• The ability to do work

• The amount of matter to do in an object

• How much space an object takes up

What type of force causes an object to move?

• unbalanced

• balanced

• gravity

• kinetic

When a rubber band is stretched out all the way, what type of energy does it have?

• gravitational

• kinetic

• potential

• balanced

When a roller coaster is racing down the hill, what type of energy does it have?

• kinetic

• potential

• unbalanced

• gravitational

What is force?

• The amount of matter in an object that can cause objects to start moving, stop moving, or change direction

• A push or pull on an object that can cause objects to start moving, stop moving, or change direction

• The ability to do work

• How much space an object takes up

What does the law of conservation of energy state?

• Energy cannot be created or destroyed

• Energy can only change from one form to another

• Neither A or B

• Both A and B

How are gravity and friction similar?

• They both cause motion to stop

• They are both types of forces

• They both affect an object’s mass

• All of the above

What is friction?

• A force that pulls things toward the center of the Earth

• The energy an object has when it is in motion

• Energy that is stored in an object

• A force that occurs when two objects are touching

What is gravity?

• Energy that is stored in an object that affects their motion

• A force that pulls things toward the center of the Earth and is responsible for the weight of objects and affects their motion

• The energy an object has when it is in motion

• A force that occurs when two objects are touching

What is true about a balanced force? 

• There is only one force acting on an object.

• One of the forces acting on an object is bigger

• All the forces acting on an object are the same

• One of the forces acting on an object is smaller
