(5) Very Short Answer Questions: –
(i) Name some means of transport used in ancient time?
→ our own feet, donkey, horses, camels, elephants, and carts pulledby animals, on roads.And wooden boats, rafts, air tubes used on water transport in ancient time.
(ii) Give two examples of periodic motion?
→ Periodic Motions : (1) The swing, (2) The needle of sewing machine.
(6) Short Answer Questions: –
(i) Give two examples of transport used on land, water, and air?
→Transport used on land : 1) Bus, 2) Train. On water transport: 1) Boat, 2) Ship.
On air transport: 1) Aeroplane, 2) Helicopter,
(ii) What is distance?
→ Distance is a length measures between the place where you started your journey towards your destination.
(iii) Arrange the following lengths in their increasing magnitude:
1 meter, 1 centimeter, 1 kilometer, 1 millimeter.
→ 1 millimeter, 1 centimeter, 1 meter, 1 kilometer.
(iv) Write the similarities and differences between the motion of a bicycle and a ceiling fan that has been switched on?
→ The major similarities and difference between the motion of a bicycle and a ceiling fan is, both objects are moving but when we switched on the ceiling fan the wings of fan starting moving in rotation it called circular motion. And motion of bicycle (wheel) from straight line on a road so it called linear motion.
(v) The distance between Radha’s home and her school is 3250 m. Express this distance into km?
→ As per standard rule, when, 1000 m = 1 km. Radha’s home and her school is 3250 m. so, total distance is 3.250 km.
(6) Long Answer Questions: –
(i) Describe what precautions should be taken while measuring length or breadth of an object?
→We can get precautions should be taken while measuring length or breadth of an object is, when we can take measurement of small cardboard box we use scale for it, place zero on one edge of the box and see on which reading of scale the other end. The scale must be parallel to the length which is being measured. In this case if we take the scale is not kept parallel to the length of box. We observe the difference of first reading from second reading will be the length of the box. Damage of scale first reading also not correct give us correct dimensions.
(ii) How many types of motion are there? Give examples for each type?
→ There are three types of motions : (1) Linear Motion: – This type of motion an object motion in a straight line. For example, a moving car or bus on straight road, train running on a track.
(2) Circular Motion: – This type of motion an object motion along circular path. For example, motion of ceiling fan wings, and hands of a clock.
(3) Periodic Motion: – This type of motion an object motion repeats its motion after fixed interval of time. For example, the swing, sewing machine’s needle is moving up and down.
(iii) Write an activity for measuring the length of a curved line?
→ We cannot be able to measure the length of a curved line directly by using any type of scale or meter scale. At that time, we can use thread to measure the length of curved line.So, we need lot of care to measure correct measurement. We need standard units and devices when we able to submit our correct result.
(iv) Why handspan or foot steps cannot be used as standard units of measurement?
→We cannot use handspan or foot stems be used standard units of measurement
Because, ancient people use to measure it at that time. There is difference between person to person, in this measurement we found inaccurate result many types of flows. The footsteps or handspan cannot cover proper dimension.
In this modern age we have standard units, and devices to measure all things, so, we cannot used handspan or foot for standard units of measurement.
