Answer 1

Required Answers:-

1) Velocity is defined as displacement per unit time.

2) Speed is scalar quantity and velocity is vector quantity.

3) If speed of a body is continuously decreasing, the body is said to be in retardation/ negative accleration

4) Acceleration is vector quantity and its Sl unit is m/s²

5) A physical quantity that has magnitude as well as direction is called vector quantity.

6) The slope of velocity-time graph gives accleration and the slope of displacement-time graph gives velocity.

Note:

• All the above questions are based on basic concepts of Kinematics (or Mechanics.)
• It is all about motion of a body$.$
• Distance, Displacement, Speed, Velocity and accleration are all types of measures.
• Graphs of these quantities gives varieties of information like slope of velocity time graph gives accleration and area gives the displacement.

Answer 2

Answer:

Required Answer :-

1. Displacement
2. vector
3. retardation
4. m/s²
5. direction
6. Acceleration and Velocity

Know More :-

• They deals with the speed, acceleration,final velocity, initial velocity, Retardation
• Retardation is the negative of acceleration.
• Displacement is the shortest distance from one place to other.
• SI unit of Velocity is m/s
• Velocity are of two types :-

1. Initial velocity :- It is the moving velocity of an object.
2. Final Velocity :- It is the constant velocity of an object.
