5th Grade Forces and Motion Application Check

Front

What is friction?

Back

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

Front

What happens to friction when a surface is smooth?

Back

Friction decreases when a surface is smooth, making it easier for objects to slide over it.

Front

What happens to friction when a surface is rough?

Back

Friction increases when a surface is rough, making it harder for objects to slide over it.

Front

What is mass?

Back

Mass is the amount of matter in an object, which affects how much force is needed to move it.

Front

How does mass affect the force needed to move an object?

Back

The greater the mass of an object, the more force is needed to move it.

Front

What is the relationship between force and motion?

Back

Force is needed to change the motion of an object; without force, an object will remain at rest or in uniform motion.

Front

What is an example of increasing friction?

Back

Rolling a ball on gravel increases friction compared to rolling it on a smooth surface.

Front

What is an example of decreasing friction?

Back

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

Front

Why is it harder to walk on ice?

Back

Ice decreases friction, making it slippery and harder to walk on.

Front

What is the effect of applying force to a heavy object?

Back

Applying force to a heavy object requires more effort due to its greater mass.
