A car is moving with constant acceleration. Which of the following is true?

a) the car travels the same distance in each second
b) car's velocity increases by the same amount in each second
c)car's velocity decreases by the same amount in each second
d)car's velocity changes by the same amount in each second

acceleration is the change in velocity so that would mean that d) is the correct answer right?

correct.

Yes, you are correct. The correct answer is d) The car's velocity changes by the same amount in each second.

To explain this, we need to understand the relationship between acceleration, velocity, and time.

Acceleration is defined as the rate of change of velocity with respect to time. In other words, acceleration is how much the velocity of an object changes per unit of time.

When a car is moving with a constant acceleration, it means that its velocity is changing by the same amount in each second. This implies that the car's acceleration remains constant over time.

Option a) states that the car travels the same distance in each second, which is not necessarily true. The distance traveled by the car depends on its initial velocity, the acceleration, and the time elapsed.

Option b) suggests that the car's velocity increases by the same amount in each second, which is incorrect. The amount by which the car's velocity increases depends on the magnitude of the acceleration.

Option c) states that the car's velocity decreases by the same amount in each second, which is also incorrect. Again, the amount by which the velocity decreases depends on the magnitude of the acceleration.

Therefore, option d) is the correct answer since the car's velocity changes (increases or decreases) by the same amount in each second when it is moving with a constant acceleration.
