Answer 2

What can you deduce about the resultant force acting on an object that is

(a) moving at a constant speed in a straight line?

(b) accelerating?

Resultant force when speed is constant is 0 because acceleration is 0. F = Mass × Acceleration

and when it is accelerating then force is directly related to acceleration.
