Effect of Location on Mass and Weight

Q. A man weighs 600 N on the earth. What is his mass? (take $g=9.8m{s}^{-2}$). If he were taken to the moon, his weight would be 100 N. What is his mass on the moon? What is the acceleration due to gravity on the moon? [3 MARKS]

Q.

Define the term weight of a body.

Q.

Why does a man weigh less on the moon as on the Earth?

1. Mass of the moon is less than the Earth, therefore, the force of attraction is less.

2. Mass of the moon is more than the Earth, therefore, the force of attraction is more.

3. Mass of the moon is equal to that of the Earth.

4. Can't be said.

Q.

A man weighs $600N$ on the Earth. If he was taken to the Moon, his weight would be $100N$. What is the acceleration due to gravity on the Moon? (Take $g=10m{s}^{-2}$)

1. $1.66m{s}^{-2}$

2. $2.66m{s}^{-2}$

3. $0.66m{s}^{-2}$

4. $1m{s}^{-2}$

Q.

The mass and weight of a body remains the same any where in the universe.

1. True

2. False

Q. 1. Weight of an object on the moon is 1/6th of its weight on the earth. True or False?
2. How much would a 70 kg man weigh on the moon? What would be his mass on the earth and on the moon? (Acceleration due to gravity on moon $=1.63m/s^2$)

Q.

Answer in one statement:

What is weight?

Q.

Write the formula to find the weight of an object.

Q.

If an object weighs 80 N on earth, then find out its weight on moon.Take g on earth $=10m{s}^{-2}$

1. 10 N

2. 40.33 N

3. 13.33 N

4. 80 N

Q.

An astronaut weighs 840 N on Earth, what would his weight be on the Moon?

1. 120 N

2. 100 N

3. 840N

4. 140 N

Q.

The quantity of matter contained in an object is called mass. It remains constant whether the object is on earth, the moon, or even in outer space. Weight on the other hand is the force of attraction of the earth with which an object is attracted towards the earth. Now, suppose a man weighs $600$ N on earth, his weight on moon would be $100$ N.

Acceleration due to gravity on the moon is

1. $10m/s^2$

2. $9.8m/s^2$

3. $1.66m/s^2$

4. $1m/s^2$

Q.

What is more fundamental mass or weight?

Q.

A boy having has a weight of 600 N on Earth. What would be his weight on the Moon? (g = 10 m/s²)

1. 500 N

2. 600 N

3. 700 N

4. 800 N

Q.

A boy weighs $600N$ on the Earth. What would be his weight on the Moon? (acceleration due to gravity of earth $g=10m/s^2$)

1. 100 N

2. 200 N

3. 600 N

4. 400 N

Q.

A boy weighs 600 N on the Earth. What would be his weight on the moon? (acceleration due to gravity on moon = $\frac{1}{6}th$ acceleration due to gravity on earth)

1. 100 N

2. 200 N

3. 600 N

4. 400 N

Q.

The weight of a body is determined as______.

1. m x g

2. m/g

3. $\frac{g}{m}$

4. $\frac{1}{m\times g}$

Q. If the radius of the earth shrinks by 4% and there is no change in its mass, the value of g increases by ___ %.

Q.

A man weighs 600 N on the equator, but when he moves to the pole he finds a slight increase in his weight. This is because:

1. Radius of the Earth is less at poles since it is not a perfect sphere

2. Radius of the Earth is more at poles since it is not a perfect sphere

3. There is no increase or decrease in weight on the Earth

4. Can't be said

Q.

Consider the following statements:
A. The acceleration due to gravity of the moon is equal to that of the earth.
B. The acceleration due to gravity of the moon is less than that of the earth.
Which of these statement(s) is/are correct?

1. Neither A nor B
2. A only
3. B only
4. Both A and B

Q.

A boy have a mass of 50 kg. What would be his weight on the Earth? ($g=10m{s}^{-2}$)

1. 500 N

2. 600 N

3. 700 N

4. 800 N

Q.

A boy weighing $600N$ is in a lift. If the lift experiences a breakdown and starts falling freely under the action of gravity, what would be the apparent weight of the boy in the lift?

1. $600N$

2. $100N$

3. $0N$

4. $400N$

Q. A man weighs $600N$ on the equator, but when he moves to pole he finds a slight increase in his weight. This is because:

1. Radius of the Earth is more at poles.
2. Radius of the Earth is less at poles.
3. Mass of earth is less concentrated near poles.
4. The magnetic field is higher at poles than that at the equator.

Q. The mass of an object measured on the moon is its mass measured on the earth.

1. equal to
2. greater than
3. less than
