Question

explain at least four effect of force with a suitable example for each ​

Answer 1

ANSWER :

━━━━━━━━━━━━━━━━━━━━━━━━━

1. A force is capable of changing the speed of an object I.e it can make a stationary object move and vice versa.

$\sf\green{ </strong><strong>Example</strong><strong>}$

• when a person pushes a stationary car it gets into motion which means that the speed of the car increases from 0 to some numerical value.

━━━━━━━━━━━━━━━━━━━━━━━━━

⠀⠀⠀2. A force can change the direction of a moving object .

$\sf\green{ Example}$

• in the game of snooker when a cue ball (white colour) is hit , it get into motion and hit the other ball changing their directions

━━━━━━━━━━━━━━━━━━━━━━━━━

$\sf\green{ Example}$

⠀⠀⠀3. A force can change the shape of an object.

$\sf\green{ Example}$

• if we have to take out lemon juice from lemon we apply a certain force in order to squeeze it which results in change in its shape.

━━━━━━━━━━━━━━━━━━━━━━━━━

⠀⠀⠀4.A force can change the state of an object(rest to motion/ motion to rest)

$\sf\green{ Example}$

• A heavy box at rest is pushed to move it from one room to another. This changes the state of motion of the box.

Answer 2

Ans=The effects of force of an object

The effects of force of an objectWe all might have heard about force. We use the word force on a daily basis. Force has become a common word rather than scientific word. So let us first know what a force is.

• Following are the effects of force on an object

1) Force can set a stationary object in motion:

• When force is applied on a stationary object, the object tends to move in the direction in which force is applied. For example, applying force on a stationary tennis ball will make it continue its motion in the direction of applied force.

2) Force can either stop or slow down the moving object:

• Force needs to be applied on a moving object either to stop it or to slow down the object. For example, the moving ball can be stopped by applying external force.

3) Force is applied to change the direction of moving object:

• The direction of a moving object can be changed by applying the force on that object. For example, the direction of the moving football can be changed by applying force at an angle such that the direction is changed.

4) The shape of an object can be changed by applying force:

• Consider a rod which is circular in shape, by hammering the rod which is applying an external force, the rod can be turned into a flat sheet.
