Forces and Motion Concepts

What is a force in science?

• A type of energy

• A push or a pull on an object

• The speed of an object

• The weight of an object

When you throw a ball, what are you doing to it?

• Making it lighter

• Exerting a force on it

• Changing its color

• Making it disappear

What is the force that pulls all objects towards the Earth?

• Friction

• Wind

• Gravity

• Magnetism

If the forces acting on an object are balanced, what will the object do?

• Speed up

• Stay still

• Change direction

• Float away

What happens to an object when the forces acting on it are unbalanced?

• It stays in the same place.

• It gets heavier.

• It starts to move.

• It disappears.

What does it mean for an object to be in motion?

• It is very heavy.

• It is changing its position.

• It is standing still.

• It is pushing something.

What is velocity?

• How much an object weighs.

• The color of an object.

• The speed and direction of an object's motion.

• The sound an object makes.

What is acceleration?

• When an object stops moving.

• A change in an object's velocity.

• The size of an object.

• The force of gravity.

What do Newton's Laws of Motion help us understand?

• How plants grow

• How forces and motion work

• How to build a house

• How to cook food

What happens to an object that is not moving if no outside force pushes or pulls it?

• It will start moving on its own

• It will stay still

• It will get lighter

• It will disappear
