2.There are two equal forces acting on an object . In which direction will the object
move? Do you think this information is correct to answer the question?
3. How can we describe force?
4. Enlist the effects of force.
5. For a force to come into play, objects must interact with each other. Justify the
statement by giving examples.
6. A girl is pushing a box towards west. In which direction should her friend push the
box so that it moves faster in the same direction?
7. Specify the action(push /pull) of forces in the following :
a. Plastic scale pressed between two bricks.
b. Squeezing a piece of lemon.
c. A football player taking a penalty kick.
d. Moving a box placed on a table.
e. Opening a drawer.
8. List the effects of force in the following situation:
a. A rubber band suspended from a nail fixed on a wall.
b. A lump of dough on a plate.
Answers
The answers are as follows :
2).No , this information is not enough to answer this question . It is necessary to know the direction in which the force is acting .
3).A force can be defined as a push or pull which when applied on a body can change the shape , size or state of a body.
4).The following are the effects of a force :
- It can move a stationary object .
- It can stop a moving object .
- It can change the velocity of a moving .
- It can change the shape and size of a object .
5).No body is not necessary to be in contact , as for example if a body is in the air the earth applies gravitational force on it even it is not in contact ith the earth .
6).She should also push in the west direction , so that the force will sum up and body will move faster .
7). a> Push
b>Push
c> Push
d> Push or pull
e> Pull
8). a> When the rubber band will be stretched , its shape will be
changed.
b>When the force is applied on the lump , its shape will be
changed.
