1 A ball of paper will fall faster than a sheet of
paper
because
Ans.

2. A parachute with large canopy takes a longer time to reach on the ground.
Ans.

3. Accidents due to skidding of motorbikes are more common during rainy
season.
Ans.

4. If 2 objects of the same weight are dropped from 2 different heights,
the object dropped from lower height will reach the ground first.
Ans.​

Answer 1

Answer:

Answer 1- Because the air friction will be felt more on the sheet of paper due to having more surface area than a ball of paper.

Answer 2- Because air friction is felt more on a surface with a larger surface area.

Answer 3- During rainy season, friction on the roads is reduced as layer of water covers the road which makes the surface slippery and motorbike tyres find it difficult to hold the ground.

Answer 4- That's because both the objects will drop with similar velocity (9.8 m/s if air friction is neglected) and since time is indirectly proportional to distance,the object dropped from the lower height will reach the ground first.
