Momentum

lilianermegard — 2024-03-21 12:09:49 UTC

Momentum is referred as a measure of how difficult it is to stop a moving object.

If there is an object with more mass or higher velocity, it gets harder to stop the object from moving.

P=m*v (momentum=mass*velocity)

We use the SI units such as:

Mass (kg)

Velocity (m/s)

Momentum (kg*m/s)

This is referred as a sudden force or desire, something happens more quickly than it usually would.

Impulse=F△t

(impulse=Force delta time)

The relation between impulse and momentum has the formula: F△t=△p

If two particles move and then collide, they will stick together and move as one particle. What will be the shared velocity?

Particle A: 10kg (m), 100m/s (v), 1000 kg m/s (p)

Particle B: 3kg (m), 70 m/s (v), -210 kg m/s (p)

Total momentum (p)= 1000+(-210)=790 kg m/s

Total mass (m)= 10+3=13 kg

Shared velocity= momentum/mass= 790/13= 60,7692308=60,8 m/s
