Front

What is the normal force acting on an object at rest on a horizontal surface?

Back

The normal force is equal to the weight of the object when it is at rest on a horizontal surface.

Front

What is the formula to calculate weight?

Back

Weight (W) = mass (m) × acceleration due to gravity (g), where g is approximately 9.8 m/s² on Earth.

Front

What property of an object changes when it is on a different planet?

Back

Weight changes because it depends on the gravitational pull of the planet, while mass remains constant.

Front

Calculate the weight of a 6.0 kg bowling ball on Earth.

Back

Weight = mass × gravity = 6.0 kg × 9.8 m/s² = 58.8 N.

Front

What is the relationship between mass and weight?

Back

Weight is the force exerted by gravity on an object's mass.

Front

How do you calculate the force experienced by an object given its mass and acceleration?

Back

Use Newton's second law: Force (F) = mass (m) × acceleration (a).

Front

What is the weight of a 2.00 kg box on Earth?

Back

Weight = 2.00 kg × 9.8 m/s² = 19.6 N.

Front

If an object has a weight of 24 N, what is its mass?

Back

Mass = weight / gravity = 24 N / 9.8 m/s² ≈ 2.45 kg.

Front

What is the unit of force in the International System of Units (SI)?

Back

The unit of force is the Newton (N).

Front

What does a normal force represent in physics?

Back

The normal force is the support force exerted upon an object that is in contact with a stable surface.
