P2 - What's the difference between mass and force?? Watch

1. So I was revising about resultant forces and Hooke's Law and for resultant force, it was measured in Newtons and for mass it was also measured in Newtons....? So what's the difference?

Thanks
2. Sounds like a mistake to me. Mass is measured in kilograms, not Newtons.

Mass describes the quantity of matter an object contains. Force is any influence that can cause something with mass to accelerate.

It's a mistake. Mass isn't measured in Newtons. Weight is.

Mass should not be measured in Newtons*: it is measured in kilograms. Weight (mass*gravity - gravity is an acceleration of, on Earth, 9.81ms^-2) is measured in Newtons.

Mass is how much stuff there is and weight is the force pulling you down to the Earth. Generally, a force is an interaction acting on a body which, assuming no opposition, will change its motion.

*Newtons in SI units is kgms^-2
5. mass is in kilograms (kg)
weight is in newtons (N)

Spoiler:
Show
because I think that mass is the amount of matter whereas weight is a force
6. Okay thanks everyone!
