Weight VS. Mass

The weight is defined as:

• The amount of force exerted on the body due to the gravity.

• The amount of matter that object has.

• The amount of energy in the object.

what is the unit of the weight?

• Kg

• N

• g

• fg

where the weight of 5kg object is greater

• on the moon

• in the space

• on the earth

what is the value of gravitational field (g) near the surface of the earth?

• 0 N/kg

• 1.6 N/kg

• 9.81 N

• 9.81 N/kg

explain why the weight of the object on the earth is greater than its weight on the moon?

• The gravitational field g of the Earth is Less than the gravitational field of the Moon.

• The gravitational field g of the Earth is greater than the gravitational field of the Moon.

• The gravitational field g of the Earth is equal to the gravitational field of the Moon.

which object has the greater weight near the surface of the ground?

• car of mass 1500Kg

• car with mass 500 kg

• car with mass 2500kg

• car with mass 1000kg

Which quantity will change of the object as it travel away from the earth to the space?

• its mass

• its weight
