Question

TLO :----

1.How can we define motion?
2.Can we tell the position of any objec withot taking name of another object
3. What is areference point
4 What is displacement?
5 What is difference between distance & displacement?
6. Is it possible that an object covers a long
distance and there is still no displacement?
7.Do you need to tell the directio while descrbing the displacement of an object
Wat is the SI unit of displacement?​

Answer 1

Answer:

1. a body is said to be in motion when its position changes continuously with respect to stationary object taken as a reference point with time.
2. yes,for example when the position of a car changes continuously with respect to stationary objects like house and trees etc. we say that the car is moving or that the car is in motion.
3. reference point is a stationary object with which the position of an object is protected.
4. the shortest path between the initial and final position of a body along with direction is known as displacement.
5. when a body moves from one point to another the distance travelled refers to the actual length of the indirect part whereas displacement refers to the straight line path between initial and final position. distance is a scalar quantity and displacement is a vector quantity.
6. yes it is possible that an object moves a certain distance but still the displacement is zero when the initial and final position of the object is same.
7. displacement has magnitude as well as direction so it is important to notify the direction.

• SI unit of displacement is metre per second.

Answer 2

Answers:

1.motion means displacement or change in the position of an object over time. It can be described in terms of displacement, distance, velocity.

4.Displacement is defined to be the change in position of an object.
