Give an example each of the type of motion when
a) acceleration is in the direction of motion
b) acceleration is against the direction of motion
c) acceleration is uniform
Answers
Answer:
a)In each case, the acceleration of the object is in the positive direction. In Example A, the object is moving in the positive direction (i.e., has a positive velocity) and is speeding up. When an object is speeding up, the acceleration is in the same direction as the velocity.
b)If an object is slowing down, then its acceleration is in the opposite direction of its motion. This general principle can be applied to determine whether the sign of the acceleration of an object is positive or negative, right or left, up or down, etc. Consider the two data tables below.
c) A body has uniform acceleration if it travels in a straight line and its velocity increases by equal amounts in equal intervals of time. For example, a freely falling body has uniform acceleration.motion

Answer:
1. Acceleration of a body when it is moving due to an external force.
2. Acceleration offered by the friction when a body is moving.
3. Acceleration during free fall of a body.
