How to calculate time needed by an object to change its state of motion when an net force applies to it (inertia)?
(Newton's first law states that every object will remain at rest or in uniform motion in a straight line unless compelled to change its state by the action of an external force. This tendency to "...

In a moving car / bus when the car suddenly accelerates do we go back due to inertia or is it due to pseudo force?
When an car moves forward we go back and we have always read that the reason was that our legs stay in contact with the ground and our body goes back since it was at rest and with sudden motion it ...

Does it take more energy to bring a car to a halt if it is still accelerating on impact than travelling at constant speed?
So, my physics is quite rusty, been out of varsity for a while.
A friend asked me this and I am still pondering. Here is the scenario:
2 Cars are travelling towards a wall, and make impact with the ...

Doubt regarding lifts (and inertia?)
so i was thinking about lifts and i am confused.
let's say there is a body within a lift (system at rest). Now if the lift starts to accelerate downwards with say an acceleration a ($a>g$). The ...

How density of fluids is would affect inertia?
I was watching that movie Event Horizon and they use water as an instrument to protect passengers of a space vessel from 30G acceleration, so my question is about a similar scenario, what would happen ...

What happens to the acceleration from an initial force according to the law of inertia?
Say we hit a golf ball with a club. Hitting the ball requires a force = m*a. According to the law of inertia, velocity should be constant, but how can that velocity be constant if we hit the golf ball ...

Which is true: objects keep spinning because of inertia, or objects keep spinning because of centripetal force?
I'm hoping any gravity or friction can be ignored.
I gather a spinning object is a non-inertial frame. I suppose that's because change of direction is acceleration. Continued acceleration requires ...

Has anyone directly observed the equivalence of inertial and gravitational mass for the electromagnetic force?
Before someone tells me to drop a bowling ball and feather off the Leaning Tower of Pisa in a vacuum, let me point out that, in general relativity, you can't deduce anything about either mass of a ...

Is pseudo force another form of inertia observed from accelerating frame of reference?
We know that pseudo forces act when we opt for non-inertial frames of reference.

In the context of General Relativity, does having gravitational mass imply resistance to acceleration?
My question is essentially this one, but since that one never got a satisfactory answer, and it's of such fundamental concern, I'd like to try asking it in a different way.
The question is whether ...

When a car accelerates relative to earth, why can't we say earth accelerates relative to car?
When a car moves away from a standstill, why do we say that the car has accelerated? Isn't it equally correct to say that the earth has accelerated in the reference frame of the car? What breaks the ...

Why does mass limit acceleration?
If a force of $10\,\mathrm{N}$ is applied to different objects of different mass in empty space, in the absence of gravity, why do lighter objects accelerate faster than heavier objects? Why does mass ...

What if inertial and gravitational mass were different?
It's well known and heavily documented that gravitational and inertial mass are identical.
This has been experimentally tested to many digits of precision.
But nothing I've seen ever describes how ...

Are falling objects harder to push compared to objects at rest
While an object is still in the air falling under the influence of gravity, does it take greater force to push or steer it to the side compared to when the object is in a state of rest?

How do you apply each of Newton's laws to specific scenarios?
The 3 Newton's laws of motion are easy to be understood but examples citing which law caused it are so confusing - say a bullet fired from a gun - many people state it cause is 3rd Law - but I see all ...
