2nd Law of Motion: Mass vs Weight

Front

What is the formula to calculate weight?

Back

Weight = mass × acceleration due to gravity (W = m × g)

Front

How does weight change when an object is on the Moon compared to Earth?

Back

Weight decreases on the Moon due to lower gravitational acceleration.

Front

What is the acceleration due to gravity on Earth?

Back

9.8 m/s².

Front

What is the acceleration due to gravity on the Moon?

Back

1.63 m/s².

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.

Front

What is an unbalanced force?

Back

An unbalanced force is a net force that causes an object to accelerate.

Front

What is the normal force?

Back

The normal force is the force exerted perpendicular to the surface an object rests on.

Front

True or False: A force is required to keep an object in motion. Why?

Back

False. An object in motion will remain in motion unless acted upon by an unbalanced force (Newton's First Law).

Front

What happens to an object's weight if its mass remains constant but it is taken to a location with different gravitational acceleration?

Back

The weight will change according to the local gravitational acceleration.

Front

What is the relationship between mass and weight?

Back

Weight is directly proportional to mass; as mass increases, weight increases.
