2.3.7 Forces and Newton's laws

Card 1 of 22

What force acts vertically downwards on a particle, and what is its magnitude?

A

For horizontal particles A and B pulled by PPP, their equations are T=mAa\boxed{T=m_Aa}T=mA​a​ and P−T=mBaP-T=m_BaP−T=mB​a.

B

Both forces act on the same object.

C

Its weight, of magnitude mgmgmg.

D

The string becomes slack, so the connected-particle model fails.
