When the velocity of a body increases by equal amounts in equal intervals of time, this is known as?

• A. Uniform speed
• B. Uniform acceleration
• C. Constant velocity
• D. Instantaneous acceleration

Answer: (B)

When the velocity of a body increases by equal amounts in equal intervals of time, this behavior is described as uniform acceleration. This means that the acceleration, defined as the rate of change of velocity, remains constant over time. For example, if a car accelerates from 0 to 10 m/s in the first second, and then from 10 to 20 m/s in the second second, the increase in velocity is consistent across each time interval. Uniform acceleration contrasts with constant velocity, where the speed and direction of the object remain unchanged. This scenario would indicate no change in velocity, and thus no acceleration occurs. Instantaneous acceleration refers to acceleration at a specific moment in time, rather than over a consistent duration, which also does not align with the definition provided. Lastly, uniform speed implies that the object covers equal distances in equal intervals of time but does not specifically address changes in velocity; hence it does not capture the essence of uniform acceleration.
