Q. 93.7( 112 Votes )
State which of the following situations are possible and give an example for each of these:
(a) An object with a constant acceleration but zero velocity.
(b) An object moving in a certain direction with an acceleration in the perpendicular direction.
(a) The above given situation is possible. For example, when a ball is thrown up at maximum height, it has zero velocity, although it will have constant acceleration due to gravity, which is equal to 9.8 m/s 2. This situation can be explained by the given graph below
(b) The above given situation can be seen in the following example:When a car is moving in a circular track, its acceleration is perpendicular to its direction.This situation can be explained by the given graph below.

There is an argument about uniform acceleration between Mr X and Mr Y. Mr X says “acceleration means that farther you go faster you go”. Mr Y says “acceleration means that longer you go the faster you go”. Whose statement is correct?Evergreen - Science

You are sitting in a stationary car. There is a helium balloon tied to its floor. You accelerate and obviously feel like you are being pushed backwards (against the direction of your accelerations). The balloon.All In One - Science
