Deceleration has actually referred to the acceleration in a reverse way. Acceleration is denoted by a. Give one example for each of the type of motion when i Acceleration is in the direction of motion ii Acceleration is against the direction of motion iii Acceleration is uniform.
Answer- The man released the rock from rest therefore we get the initial velocity as 000 ms. Or Change in velocity per unit time is also known as acceleration. 1 Answer 1 vote.
Thus acceleration means the rate at which an object speeds up deceleration means the rate at which an object slows down. SI unit is ms -2. The acceleration is taken to be positive if it is in the direction of velocity and negative when it is opposite to the direction of velocity.
V f 0 98018 v f 1764 ms -1. When the speed of body is changing with respect to time acceleration is formed. It is denoted by symbol a and is articulated as- The SI unit for acceleration is meter per second square or ms 2.
