Question

Conclusion When there is a constant unbalanced force applied in the same direction as the motion, speed will ___________________ and acceleration will _____________________________. When there is an increasing unbalanced force applied in the same direction as the motion, speed will ___________________ and acceleration will ________________________. When there is a constant unbalanced force applied in the opposite direction as the motion, speed will ___________________ and acceleration will ________________________. When there is an increasing unbalanced force applied in the opposite direction as the motion, speed will ___________________ and acceleration will ________________________.

Answer 1

Explanation:

When there is a constant unbalanced force applied in the same direction as the motion, speed will increase and acceleration will remain constant. When there is an increasing unbalanced force applied in the same direction as the motion, speed will increase and acceleration will increase.

According to newton's 2nd law

F = ma

F ∝ a

meaning when F increases , a increases and vice versa
