Question

A constant force is applied to an object, causing it to accelerate at 8.0 m/s2. What will the acceleration be if 

1. The force is doubled?
2. The object’s mass is doubled?
3. The force and the object’s mass are both doubled?
4. The force is doubled and the object’s mass is halved?

Answer 1

A constant force is applied to an object, causing it to accelerate at 8.0 m/s2. What will the acceleration be if 

1. The force is doubled?
2. The object’s mass is doubled?
3. The force and the object’s mass are both doubled?
4. The force is doubled and the object’s mass is halved?

Force = Mass * acceleration

If force is doubled and mass is unchanged, acceleration will be doubled

If mass is doubled , acceleration will become half for same force

If force and mass both are doubled , acceleration is unchanged

If force is doubled and mass is halved, acceleration gets four times
