Give one example each of the type of motion when
1. Acceleration is in the direction of motion
2.Acceleration is against the direction of motion
3.Acceleration in uniform
Answers
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.
Answer:
1. Acceleration is in the direction of motion- A car travelling in such a way that its velocity changes at constant rate.
2. Acceleration is against the direction of motion- when ball is thrown upwards.
3.Acceleration in uniform- a skydiver jumping out of a plane
Explanation:
If an object's velocity changes, it is said to have been accelerated. An object's velocity can alter depending on whether it moves faster or slower or in a different direction. A falling apple, the moon orbiting the earth, and a car stopped at a stop sign are a few instances of acceleration. Through these illustrations, we can see that acceleration happens whenever a moving object changes its direction or speed, or both.
Acceleration is defined as rate of change of velocity.
1. Acceleration is in the direction of motion- A car travelling in such a way that its velocity changes at constant rate.
2. Acceleration is against the direction of motion- when ball is thrown upwards.
3.Acceleration in uniform- a skydiver jumping out of a plane
