The gravitational force that an object exerts due to its mass is called:

• weight.

• mass.

• friction.

• acceleration.

An astronaut with all of the necessary gear has a weight of 2,250 N on Earth (acceleration due to gravity on Earth is 9.8 m/s/s). If the acceleration due to gravity is 1.63 m/s/s on the Moon, what would the astronaut weigh on the surface of the Moon?

• 375 N

• 519 N

• 950 N

• 2150 N

If Earth's mass was cut in half, what would happen to your mass?

• increase because gravitational force increases
• decrease because gravitational force decreases
• decrease because gravitational force increases
• nothing, mass is not affected by gravitational force

What is the definition of weight?

• a measure of how much matter an object has

• a measure of force of gravity on an object

• the force an objects pushes on the ground

• the force on an object due to its size

The force of gravity on Jupiter is a little more than 2 times the gravitational force on Earth. If an object has a mass of 50 kg and a weight of 490 N on Earth, what would be the object's approximate mass and weight on Jupiter?

• 50 kg and 490 N
• 100 kg and 490 N
• 50 kg and 980 N
• 100 kg and 980 N

What device is used to measure weight?

• a triple beam balance

• a spring scale

• stopwatch

• meter stick

The force exerted perpendicular to the surface an object rests on is known as:

• the normal force.

• friction.

• gravity.

• the electromagnetic force.
