24-25 Forces and Newton Laws REVIEW

Front

What is the Normal Force?

Back

The Normal Force is the force exerted by a surface to support the weight of an object resting on it, acting perpendicular to the surface.

Front

What is Newton's Second Law of Motion?

Back

Front

If the force is constant and the mass is doubled, what happens to the acceleration?

Back

The acceleration is halved (cut in half).

Front

What unit is force measured in?

Back

Force is measured in Newtons (N).

Front

What are Unbalanced Forces?

Back

Unbalanced Forces are forces that cause an object to accelerate, resulting in a change in motion.

Front

What are Balanced Forces?

Back

Balanced Forces are equal in size and opposite in direction, resulting in no change in motion.

Front

What is Gravitational Force?

Back

Gravitational Force is the attractive force between two masses, such as the Earth and an object, pulling the object towards the center of the Earth.

Front

What is Friction Force?

Back

Friction Force is the force that opposes the motion of an object, caused by the contact between two surfaces.

Front

What is the formula for calculating force?

Back

Front

What happens to the acceleration if the mass is increased while keeping the force constant?

Back

The acceleration decreases.
