What is gravitational force?

Back

The force of attraction (pulling) between two objects. Every object experiences this force on Earth.

Front

What is frictional force?

Back

The force that resists motion between two surfaces.

Front

What is applied force?

Back

The force exerted on an object by a person or another object.

Front

What is normal force?

Back

The support force exerted upward on an object in contact with a surface.

Front

What happens when the applied force is greater than the frictional force?

Back

The object will start to move.

Front

What is the relationship between mass and gravitational force?

Back

The gravitational force increases with the mass of the objects involved.

Front

How does friction affect motion?

Back

Friction opposes the motion of an object, making it harder to move.

Front

What is the effect of surface texture on friction?

Back

Rough surfaces have higher friction than smooth surfaces.

Front

What is the role of normal force in motion?

Back

Normal force supports the weight of an object and prevents it from falling through a surface.

Front

What is the difference between static and kinetic friction?

Back

Static friction prevents motion, while kinetic friction acts on moving objects.
