Tree falling without inertia while people stay suspended in air for a split second due to inertia
I recently saw a video ( watch it 0.5x speed ) of a slanted coconut tree on the bank of a river in India breaking due to the weight of the kids who climbed on it.
The tree seems to have broken near ...

What causes a rotating object to rotate forever without external force—inertia, or something else?
Someone told me that it is not inertia, but I think it is inertia, because it will rotate forever. In my understanding, inertia is the constant motion of an object without external force. Am I wrong?

Is Newton's third law due to inertia?
Newton's third law states that each force has an equal and opposite force. If I kicked a ball, it would apply the same force on me. Is this due to the ball's inertia? To clarify, is the ball exerting ...

Would you be able to get off of a frictionless surface?
Imagine that you are standing (naked) in the center of a level circular disk (with a radius of, say, 3 meters) that is completely frictionless.
Without resorting to blowing air or excreting any ...

Does inertia have anything to do with conservation of energy? [closed]
I have googled this and not found anything. It seems to me that if objects at rest did not resist being accelerated (which is what I once thought was the case in outside of gravity like in outer space)...

Does the Inertia of a Cue Ball Affect its Reflection Angle off a Resting Billiard Ball?
Consider the following Diagram in which a Cue Ball (A) of mass M is shot twice at another pool ball with identical mass M.
When the force with which the cue ball (A) is hit (v1) is increased (v2) it ...

Imagine I am standing on Earth, and pushing a tennis ball away from me. The ball moves. If it is very heavy, I will move back instead of the ball. Now consider the same scenario in outer space, where ...

Would a sneeze by a cosmonaut in a spacesuit affect his movement?
Naive question; feel free to shoot me down
It is a truism that any motion in space would continue indefinitely unless it is opposed by an external force. If a cosmonaut were to sneeze within his/her ...
