Which of the following statements about acceleration is true. Acceleration is:
A) time/ velocity
B) force/ time
C) the rate of change of displacement
D) time/ force
E) the result of an unbalanced force exerted on a body.
ANS = E
Is this correct??
Yes, that is correct. The statement "E) the result of an unbalanced force exerted on a body" accurately describes acceleration. To arrive at this answer, let's break down the given options and understand the concept of acceleration.
Option A) time/velocity: This equation does not represent acceleration. It represents the concept of average acceleration (change in velocity over a given time period), but it does not correspond to any of the given options.
Option B) force/time: This equation represents a quantity known as the rate of change of momentum, not acceleration. It is not one of the correct options.
Option C) the rate of change of displacement: This statement accurately describes acceleration. Acceleration refers to the rate at which an object changes its velocity, and velocity is the rate of change of displacement. So, option C) is true.
Option D) time/force: This equation does not represent acceleration. It does not correspond to any of the given options.
Option E) the result of an unbalanced force exerted on a body: This statement accurately describes acceleration. Acceleration occurs when an unbalanced force acts on an object, causing it to change its velocity. So, option E) is true.
Therefore, the correct answer is E) the result of an unbalanced force exerted on a body.
