Assuming these planets were similar in radius, which planets would an object weigh the most?
Estimated mass of planet (10²³ kg)
1. W 6.4
2. X 3.3
3. Y 59.7
4. Z 48.7
A. On planet W
B. On planet Y
C. On planet Z
D. On planet X
An object would weigh the most on planet Y because it has the highest estimated mass of 59.7 × 10²³ kg. Therefore, the correct answer is B. On planet Y.
The correct answer is D. Mass is the same everywhere. Weight depends on the force of gravity.
Mass is a measure of the amount of matter in an object and remains the same regardless of the location. It is a fundamental property of an object and is measured in kilograms (kg).
Weight, on the other hand, is the force exerted on an object by gravity and depends on the location and the strength of the gravitational field. Weight is measured in newtons (N) and can vary depending on the strength of the gravitational force acting on the object.
In other words, mass is a measure of the amount of material an object contains, while weight is the force with which that mass is pulled towards the center of the planet by gravity.
The correct answer is B. The gravitational force on the moon is weaker than on earth.
When a person jumps, they exert a pushing force against the ground to propel themselves upwards. However, gravity pulls them back down. The strength of the gravitational force depends on the mass of the object and the mass of the celestial body it is on. The moon has less mass than the Earth, resulting in a weaker gravitational force on the moon compared to the Earth.
Since the gravity on the moon is weaker, a person can overcome the gravitational pull more easily and can jump higher on the moon than on Earth.
The correct answer is C. The textbook has a stronger attraction to earth.
The perception of weight is influenced by the force of gravity pulling down on an object. The force of gravity depends on the mass of the object. In this scenario, the textbook has a greater mass compared to the pencil. Therefore, the textbook experiences a stronger gravitational force pulling it towards the Earth. As a result, the textbook feels heavier than the pencil.
What is the difference between mass and weight?
A. Mass depends on the force of gravity. Weight is always the same.
B. Mass depends on location. Weight depends on the force of gravity.
C. Mass measures the force of gravity. Weight measures matter.
D. Mass is the same everywhere. Weight depends on the force of gravity
When you jump, you exert a pushing force against the ground. Gravity pulls you back down. Why can a person jump higher on the moon than on earth?
A. A person weighs more on the moon than on earth.
B. The gravitational force on the moon is weaker than on earth.
C. Pushing forces are stronger on the moon than on earth
D. A person has less mass on the moon than on earth
When you hold a textbook and a pencil, why does the textbook feel heavier than a pencil?
A. Your hand repels the textbook with less force
B. You can grip the pencil with more strength
C. The textbook has a stronger attraction to earth
D. The textbook has less mass than the pencil
