A
the acceleration of an object is directly proportional to the net force acting on it, and inversely proportional to its mass.

6
Q
what happens when force increases?
A
acceleration increases at the same rate.
7
Q
which are directly proportional?
A
force and acceleration.
8
Q
what happens when mass increases?
A
acceleration decreases at the same rate.
9
Q
which are indirectly proportional?
A
acceleration and mass.
