Question
Which of the following is not correct about uniformly accelerated motion?*1 pointThe degree of slanting/steepness of the tangent to velocity time curve is a measure of the magnitude of the acceleration.The velocity-time graph of a uniformly accelerated motion is a straight line.Uniform acceleration implies the velocity of the body increases by equal amounts in equal time intervals.Uniform acceleration implies the velocity of the body decreases by equal amounts in equal time intervals.
Solution
The statement that is not correct about uniformly accelerated motion is: "Uniform acceleration implies the velocity of the body decreases by equal amounts in equal time intervals."
Explanation: Uniform acceleration refers to a constant rate of change in velocity. This means that the velocity of an object will increase or decrease by the same amount for each unit of time. However, this does not mean that a uniformly accelerated object will always decrease its velocity by equal amounts in equal time intervals. If an object is moving in a positive direction and is uniformly accelerated, its velocity will increase by equal amounts in equal time intervals. If an object is moving in a negative direction (or slowing down) and is uniformly accelerated, its velocity will decrease by equal amounts in equal time intervals. Therefore, the statement is not universally true for all cases of uniformly accelerated motion.
