Help please answer me
Answers
Answer:
Ans 1;
Distance
1) Original distance covered by the body.
2) It can never be 0.
3) It is equal or greater than displace.
4) Scaler quantity.
5) Distance is always +ve
6) Units are m/s.
Displacement
1) Shortest distance covered by the body.
2) It can be 0.
3) It is always equal or smaller than distance.
4) It is vector quantity.
5) Distance is always +ve & -ve.
6) units are m/s.
( example of both is in attachment.)
Ans 2.
Speed
1) Speed is the distance travelled by a body in unit of time.
2) Speed is scalar quantity.
3) Speed tells us how fast body is moving.
4) Speed is always positive.
5) example ;- s= d/t.
Velocity
1) Velocity is the distance travelled by a body in a particular direction in unit of time.
2) Velocity is a vector quantity.
3) Velocity tells how fast body is moving along a particular direction.
4) The magnitude of velocity of a body is positive.
5) example:- v=∆s/∆t.
Ans 3. When the velocity of a body is increasing, the body is said to be acceleration. Acceleration of a body is defined as the rate of change of its velocity with time.
Formula:- Acceleration = Final velocity-initial velocity/time taken
or
a = v - u /t.
Acceleration is vector quantity.
Ans 4.
Scalar
1) It has only magnitudes.
2) Only one dimensional.
3) The quantity changes with the change in magnitude.
4) Normal rules of algebra are applicable here.
5) One scalar quantity can divide another scalar.
6) In example of speed, time etc, the distance between points is scalar quantity not the direction.
Vector
1) It has direction and magnitude.
2) It is multi dimensional.
3) This changes with magnitude and direction.
4) There is different set of rules known as vector algebra.
5) One Vector cannot divide another vector.
6) Velocity could be example because it is measurement of the rate of change of an objects position.
