Question

A man jumping out of a slow moving bus falls forward.
a) this is due to.....
b) which Newton's Law gives the above concept? state the law
c) what is the net force acting on a book at rest on the table?​

Answer 1

Answer:

The man falls forward because of inertia of motion. The person is in a state of motion inside the moving bus. When he steps out of the bus, his lower part of the body suddenly comes to rest. But, the upper part of the body still remains in a state of motion.

ANSWER

If someone tries to get out of a moving bus then the momentum makes the person move forward. A person might fall in the forward direction due to moment of inertia when the speed is fast. This can be explained by the Newtons's law of inertia. The direction and speed of the person is the same as that of bus. As the person gets out of the moving bus the momentum is reduced to zero.

Inertia is the tendency of an object to resist any change in their state of motion. When a person alights from the bus, his body would try to continue moving in the direction the bus was moving due to inertia. But as soon as both the feet touches the ground, the lower part of the body comes to rest while the upper part gets carried away under the effect of inertia resulting into his forward fall

Answer 2

The man falls forward because of inertia of motion. The person is in a state of motion inside the moving bus. When he steps out of the bus, his lower part of the body suddenly comes to rest. But, the upper part of the body still remains in a state of motion.

• If someone tries to get out of a moving bus then the momentum makes the person move forward.
• A person might fall in the forward direction due to moment of inertia when the speed is fast. This can be explained by the Newtons's law of inertia.
• The direction and speed of the person is the same as that of bus. As the person gets out of the moving bus the momentum is reduced to zero.
• Inertia is the tendency of an object to resist any change in their state of motion. When a person alights from the bus, his body would try to continue moving in the direction the bus was moving due to inertia.
• But as soon as both the feet touches the ground, the lower part of the body comes to rest while the upper part gets carried away under the effect of inertia resulting into his forward fall.

When a person jumps out of a moving bus he runs little forward?

• A man jumping out from a moving bus holds the inertia of motion.
• As the man lands on the ground, feet come to rest instantly while the upper part of the body continue to move due to inertia of motion.
• Therefore, the person may fall forward.

Which Newton's law gives the above concept state the law?

• Newton's first law of motion, It states that a body at rest or in uniform motion will continue to be at rest or uniform motion until and unless a net external force acts on it. ​
• The first law of motion implies that things cannot start, stop, or change direction all by themselves.

Hence, Inertia of motion causes the man to fall forward. Inside the moving bus, the individual is in motion. When he gets off the bus, the bottom half of his body comes to a halt. The upper part of the body, on the other hand, is still moving.
