When a car moves with constant acceleration, the velocity-time graph is a:
Correct answer: A. Straight line
- A. Straight line
- B. Parabola
- C. Horizontal line
- D. Exponential curve
Explanation
Explanation:The slope of the velocity - time graph is equal to acceleration. As body moves with constant acceleration, the velocity-time graph will be a straight line. Slope = Constant

About Acceleration
Acceleration measures the rate at which velocity changes with time, including changes in speed, direction or both. Work includes average and instantaneous acceleration, the relation a = Δv/Δt, uniform acceleration equations, and interpreting velocity time and displacement time graphs, with acceleration carefully distinguished from velocity.

A body is moving with an initial velocity of 2 kms-1. After a time of 50 secs its velocity becomes 1.5 kms-1, Its acceleration will be:
The vertical velocity of the ball is thrown upward _ with time.
Centripetal acceleration always acts _ the center.
If the velocity of the body changes by equal amount in equal intervals of time, the body is said to have:
