Answer:

Directions: Explain how gravity affects the following activities,

1. Walking up and down the stairs.

You have to lift up your body mass under the presence of gravity, so you have to overcome the force of gravity. While climbing up the stairs you have to put force on ground, more then your weight, which put same force but in opposite direction i.e. on you.

2.Falling of leaves from the branches of the tree.

Since plants are alive, gravity has a large effect on them. For instance, a tall tree needs to get water from the ground up to the leaves at the top of the tree and gravity makes this very hard. And of course, leaves fall off trees into piles of leaves on the ground because of gravit

3.Playing jump shot.

When you shoot a basketball, you exert an upward and forward force in the direction of the net. Gravity exerts a force downward on the ball, causing it to travel in an arc as it approaches the rim. This spin creates a difference in pressure above and below the ball, and generates an upward force.
