Answer 1

Answer:

Acceleration is the rate of change of velocity.

a=v-u/t

Answer 2

Answer:

Experiments have shown that acceleration is exactly inversely proportional to mass, just as it is exactly linearly proportional to the net external force. Figure 2. The same force exerted on systems of different masses produces different accelerations.

Explanation:

Gravity affects weight, it does not affect mass. MASSES ALWAYS REMAIN THE SAME. Newton's Second Law of Motion: Force = mass x acceleration The acceleration of an object is: a) directly proportional to the net force acting on the object. ... Move it faster (greater acceleration), because there is less mass, or 2.
