Answer 2

Answer:

1. Pushes and pulls are forces.

2. If you pedal harder while cycling, the cycle moves faster. So we can say that force can make an object move from one place to another.

3. When a force is applied to an object at rest it makes the object to change its position.

4. An archer stretches her bow while taking aim at the target. She then releases the arrow, which begins to move towards the target. Based on this information fill up the gaps in the following statements using the following terms.

Contact, non-contact muscular, gravity, friction, shape, attraction

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 contact force.

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

d) While the arrow moves towards its target, the forces acting on it are due to friction and that due to attraction of air.

5. When you hit a ball with the bat you exert contact force.

6. When you knead a dough to make chapatis, the application of force can change the shape and size of an object.

7. The Earth exerts its gravity force on all objects on its surface.

Explanation:

• Force is a push or pull of an object.
• It is used to change the state of an object. For example, moving a chair or stopping a rolling stone.
• There are many types of force which are classified based on their origin, effect and application.
• The friction is a always responsible for a motion of an object. Friction is due to attraction between the object and the medium.
• The earth is a giant magnet which produces gravitation force which is a attractive force.
