For a given force as time ___
the impulse related to that force increases. *
A. increases
B. decreases

Answers

Answer:

Increases

Explanation:

For a given force, as the time increases, the impulse related to that force increases also.

Impulse and time are directly related to one another. Impulse is mathematically given as:

I = F t

I is the impulse

F is the force

t is the time taken

So, as both force and time increases, the value of the impulse must increase.

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 ________________________.

Answers

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
