5th Grade Forces and Motion Application Check

Front

What is friction?

Back

Friction is the force that opposes the motion of an object when it comes into contact with another surface.

Front

What factors affect the amount of friction between two surfaces?

Back

The amount of friction depends on the types of surfaces in contact and the force pressing them together.

Front

What is the effect of increasing friction on motion?

Back

Increasing friction slows down or stops the motion of an object.

Front

What is the effect of decreasing friction on motion?

Back

Decreasing friction allows an object to move more freely and can increase its speed.

Front

What is gravity?

Back

Gravity is a natural force that attracts two bodies toward each other, commonly experienced as the force that pulls objects toward the Earth.

Front

How does mass affect the force of gravity?

Back

The greater the mass of an object, the stronger the gravitational force it exerts.

Front

What happens to a car when the brakes are applied?

Back

When brakes are applied, friction between the tires and the road increases, causing the car to slow down and eventually stop.

Front

Why is it easier to lift lighter objects?

Back

Lighter objects have less mass, which means less force is needed to lift them.

Front

What is an example of a situation that increases friction?

Back

Rolling a ball on gravel increases friction due to the rough surface.

Front

What is an example of a situation that decreases friction?

Back

Adding wax to a bowling lane decreases friction, allowing the ball to roll more smoothly.
