Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Suppose you increase your walking speed from 1 m/s to 3 m/s in a period of 1 s. What is your acceleration?
A
2 m/s2
B
5 m/s2
C
4 m/s2
D
3 m/s2
Explanation: 

Detailed explanation-1: -Answer. Acceleration is to change in speed divided by the time for the change. Change in speed is end speed minus started speed. 3m/s-1m/s and equals to 2m/s.

Detailed explanation-2: -It simply means that the velocity of the car is increasing by 1m/s every second-Hence the units m/s per second which can be written as m/s^2.

Detailed explanation-3: -1 Answer. The object’s acceleration is-6 m/s2 .

Detailed explanation-4: -Acceleration (a) is the change in velocity (v) over the change in time (t), represented by the equation a = v/t.

Detailed explanation-5: -As we increase the force on an object the acceleration increases proportionally. Since the mass does not change as the acceleration increases, we can say that force is equal to acceleration. Therefore, if you double the force you double the acceleration.
