B) Energy that causes objects to get hotter.
C) Energy that comes from the sun.
D) Energy that helps plants grow.
B) Energy that causes objects to get hotter.
What is light energy?
A) Energy that makes things move.
B) Energy that makes things warm.
C) Energy that lets us see things.
D) Energy that makes things loud.
C) Energy that lets us see things.
What is sound energy?
A) Energy that makes things shine.
B) Energy that travels through the air and helps us hear.
C) Energy that makes objects move.
D) Energy that makes things warm.
B) Energy that travels through the air and helps us hear.
What does it mean for an object to be in motion?
A) The object stays in one place.
B) The object is changing its position over time.
C) The object is getting heavier.
D) The object is making a sound.
B) The object is changing its position over time.
What is potential energy?
A) Energy that an object has because it is moving.
B) Energy that is stored in an object and can be used later.
C) Energy that comes from the sun.
D) Energy that makes things glow in the dark.
B) Energy that is stored in an object and can be used later.
Which of the following is an example of heat energy in everyday life?
A) Ice melting in the sun.
B) A person lifting a heavy box.
C) A ball rolling across the floor.
D) A car moving down the road.
A) Ice melting in the sun.
Which of the following is an example of light energy?
A) A glowing light bulb.
B) A moving car.
C) A warm cup of tea.
D) A bouncing ball.
A) A glowing light bulb.
What causes sound energy?
A) Vibrations that move through air, water, or solids.
B) Heat that makes things warm.
C) Light that travels in waves.
D) The movement of objects through space.
A) Vibrations that move through air, water, or solids.
Sound is produced when objects vibrate, creating waves that travel through different materials to reach our ears.
What is gravity?
A) A force that makes things move faster.
B) A force that pulls objects toward each other, like the Earth pulling things toward the ground.
C) A force that makes things float in the air.
D) A force that pushes objects away from each other.
B) A force that pulls objects toward each other, like the Earth pulling things toward the ground.
Which of the following is an example of potential energy?
A) A rock sitting at the top of a hill.
B) A soccer ball being kicked.
C) A person running.
D) A car driving on a road.
A) A rock sitting at the top of a hill.
The rock sitting at the top of the hill has potential energy because it is in a position where it could fall, and gravity can cause it to move. This stored energy is released when the rock begins to move down the hill, converting into kinetic energy.
Which of the following is an example of heat energy?
A) A flashlight shining light.
B) A kettle boiling water.
C) A ball rolling on the ground.
D) A wind blowing on your face.
B) A kettle boiling water.
How does light energy travel?
A) In waves, like ripples in water.
B) In straight lines only.
C) In circles around objects.
D) In sound waves.
A) In waves, like ripples in water.
What is force?
A) The energy that makes things move.
B) The strength that makes objects change their position or shape.
C) The heat that warms up an object.
D) The light that allows us to see things.
B) The strength that makes objects change their position or shape.
8. A movement toward or backward is called a _________.
A) Push
B) Pull
C) Forward motion
D) Recoil
B) Pull
Which of the following is an example of kinetic energy?
A) A running dog.
B) A book on a table.
C) A lamp plugged into the wall.
D) A pencil sitting on a desk.
A) A running dog.
The dog is moving, which demonstrates kinetic energy. The other options involve objects that are either stationary or not in motion, making them incorrect examples of kinetic energy.

A) Light energy
B) Thermal energy
C) Kinetic energy
D) Electrical energy
B) Thermal energy
What happens when light energy hits an object?
A) It makes the object colder.
B) It can be absorbed, reflected, or passed through.
C) It makes the object heavier.
D) It makes the object move.
B) It can be absorbed, reflected, or passed through.
What happens when you pluck a guitar string?
A) The string vibrates and creates sound waves.
B) The string makes the guitar body move.
C) The string produces light that you can see.
D) The string changes into heat energy.
A) The string vibrates and creates sound waves.
A movement away or forward is called a ___________.
A) Push
B) Pull
C) Inertia
D) Friction
