Force, Motion, and Gravity

What is a force?

• A type of energy

• The speed of an object

• A push or pull that can change the motion of an object

• The color of an object

Name two types of forces.

• Acceleration, Velocity

• Gravity, Friction

• Heat, Magnetism

• Light, Sound

How does force affect the motion of an object?

• Force only affects the color of an object

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

• Force can make an object disappear

• Force has no effect on the motion of an object

Explain the concept of gravity.

• Gravity is the force that attracts objects toward each other.

• Gravity is the force that repels objects away from each other.

• Gravity is the force that has no effect on objects.

• Gravity is the force that only affects living organisms.

What is friction and how does it affect motion?

• Friction is the force that has no effect on the motion of an object.

• Friction is the force that opposes the motion of an object and it affects motion by slowing down the object.

• Friction is the force that propels the motion of an object and it affects motion by speeding up the object.

• Friction is the force that attracts objects to each other and it affects motion by increasing the speed of the object.

Give an example of balanced forces.

• Two people pushing a box with the same amount of force in opposite directions.

• A book resting on a table

• A person lifting a heavy object

• A car accelerating down a hill

What happens when forces are unbalanced?

• The object will accelerate in the direction of the greater force.

• The object will remain at rest.

• The object will move in the opposite direction of the greater force.

• The object will decelerate in the direction of the greater force.

How does gravity affect the motion of objects on Earth?

• It causes objects to move upward

• It has no effect on the motion of objects

• It causes objects to accelerate downward.

• It causes objects to move sideways

Why is it important to understand the effects of force on motion?

• To become a professional dancer

• To make cookies

• To learn a new language

• To predict and control the motion of objects
