AI Thread Summary
Momentum is defined by the equation mass multiplied by velocity. It is also described as the rate of change of force, which can be derived from the equations for force and acceleration. The relationship between momentum and force is expressed as momentum equaling force multiplied by time, known as impulse. Impulse represents the change in momentum over a specific time interval. Understanding these concepts is crucial for grasping the principles of physics related to motion.

what is the equation for momentum?
 
Physics news on Phys.org
answer

mass * velocity = momentum
 
Momentum is also the rate of change of force. This can easily be verified by rearranging the equations:

force = mass * acceleration

acceleration = velocity / seconds

momentum = mass * velocity,

Therefore:

momentum = force * seconds

Edited typo.

Integral

That's impulse, or change in momentum.

That depends. At an instantaneous point, it is momentum. But Delta Momentum = Force * Delta Time, that is impulse.
 

Thread 'Need help understanding particle physics and quantum physics'

So I know that electrons are fundamental, there's no 'material' that makes them up, it's like talking about a colour itself rather than a car or a flower. Now protons and neutrons and quarks and whatever other stuff is there fundamentally, I want someone to kind of teach me these, I have a lot of questions that books might not give the answer in the way I understand. Thanks
