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??
CORRECT
Yes, that answer is correct. Acceleration is the result of an unbalanced force exerted on a body. To understand why this is true, let's break down the other options and explain how to determine the correct statement.
A) time/velocity: This is not the correct formula for acceleration. Acceleration is the rate of change of velocity, not time divided by velocity.
B) force/time: This is not the correct formula for acceleration either. Acceleration is not directly related to time divided by force.
C) the rate of change of displacement: This statement is correct. Acceleration is indeed the rate of change of displacement over time. However, it is not one of the options provided.
D) time/force: This is not the correct formula for acceleration. Acceleration is not directly related to time divided by force.
E) the result of an unbalanced force exerted on a body: This statement is correct. Acceleration occurs when an unbalanced force is applied to a body, as described by Newton's second law of motion (F = ma).
So, among the given options, "the result of an unbalanced force exerted on a body" is the correct statement about acceleration.
