E. Answer in a sentence or two. 1. Differentiate between uniform motion and non-uniform motion. 2. What is an odometer? 3. What is a speedometer? 4. What does a distance-time graph having a straight line show? 5. What is speed? Name its SI unit.
Answers
Answer:
1. The uniform motion:- It is identical to the actual speed of the object. ... Uniform motion covers equal distance at an equal time interval.
Non-uniform motion:- It covers unequal distance at equal time interval. In uniform motion, the distance to time graph shows a straight line.
2. an instrument for measuring the distance travelled by a wheeled vehicle.
3. a piece of equipment in a vehicle that tells you how fast you are travelling.
4. the gradient of the line is equal to the speed of the object.
5. Speed = the rate at which somebody/something moves or travels. SI unit of speed is m/s ( meter per second
Answer:
1. Differentiate between uniform motion and non-uniform motion.
Ans : i) The uniform motion:- It is identical to the actual speed of the object. ... Uniform motion covers equal distance at an equal time interval.
ii) Non-uniform motion:- It covers unequal distance at equal time interval. In uniform motion, the distance to time graph shows a straight line.
2. What is an odometer?
Ans : An instrument for measuring the distance travelled by a wheeled vehicle.
3. What is a speedometer?
Ans : A piece of equipment in a vehicle that tells you how fast you are travelling.
4. What does a distance-time graph having a straight line show?
Ans : The gradient of the line is equal to the speed of the object.
5. What is speed ?
Ans : Speed is the rate at which somebody/something moves or travels. SI unit of speed is m/s ( meter per second ).
