Question

To stretch the bow, the archer applies a force that causes a change in its _________.

The force applied by the archer to stretch the bow is an example of ____________ force.

The type of force responsible for a change in the state of motion of the arrow is an example of a _________ force.

While the arrow moves towards its target, the force acting on it are due to ___________ and that due to ____________ air.

Answer 1

1. When an archer stretches the bow with a force, the bow bends.
2. This results in a change in the shape of the bow while stretching.​
3. The force applied to a body using the muscles like arms, legs are called muscular force.
4. As, an archer applies the force by using his arm, therefore the force applied by the archer is a muscular force.
5. A force that is applied on a body when due to the actual contact with the body, is termed a contact force.
6. When an arrow is on the bow, the archer applies force on it by making direct contact with it with his arms, and after release, the arrow comes into motion.
7. Thus, the motion of the arrow is due to the contact force on it.
8. When an arrow is released by the archer, it moves under gravity and after some time it hits the target while moving the arrow suffers the friction of air also.

Thus,

a) To stretch the bow the archer applies a force that causes a change in its Shape.

b) The force applied by the archer to stretch the bow is an example of muscular force.

c) The type of force responsible for a change in the state of motion of the arrow is an example of a contact force.

d) While arrow moves towards its target, the force acting on it is due to gravity and which is due to the friction of air
