Video Format solutions of all chapters are also available. Download 8 Science App for offline use. Two forces acting on the rocket immediately after leaving the launching pad are: Frictional force due to air.
Force of gravity pulling in downward direction. The force which is responsible for the attraction between the ball and the wall is electrostatic force. When we rub the balloon by a synthetic cloth, it gets charged.
When it is taken near the wall, it will get attracted towards the uncharged wall because of the electrostatic force which is the force exerted by a charged body on another uncharged body. The force acting on a plastic bucket are: Gravitational force: It is acting downwards.
Muscular force: It is applied by our hands to lift the bucket in upward direction. Although these forces are acting on the bucket but no change is found in its state of motion because the two forces are balancing each other and as a result net force is zero.
Two objects repel each other. This repulsion could be due to a frictional force only b electrostatic force only c magnetic force only d either a magnetic or an electrostatic force 2. During dry weather, while combing hair, sometimes we experience hair flying apart.
The force responsible for this is a force of gravity. Which one of the following forces is a contact force? A ball of dough is rolled into a flat chapatti. Name the force exerted to change the shape of the dough. A girl is pushing a box towards east direction.
In which direction should her friend push the box so that it moves faster in the same direction? During dry weather, clothes made of synthetic fibre often stick to the skin. Which type of force is responsible for this phenomenon?
A gas filled balloon moves up. Is the upward force acting on it larger or smaller than the force of gravity? What effect of force comes into play in this process? Two persons are applying forces on two opposite sides of a moving cart. The cart still moves with the same speed in the same direction. What do you infer about the magnitudes and direction of the forces applied.
Fruits detached from a tree fall down due to force of gravity. We know that a force arises due to interaction between two objects. Name the objects interacting in this case. Not only 8th Science solutions but other subjects are also available. Class 8 Science Chapter 11 in English Medium. A rocket has been fired upwards to launch a satellite in its orbit. Name the two forces acting on the rocket immediately after leaving the launching pad.
An inflated balloon was pressed against a wall after it has been rubbed with a piece of synthetic cloth. It was found that the balloon sticks to the wall. What force might be responsible for the attraction between the balloon and the wall?
A blacksmith hammers a hot piece of iron while making a tool. How does the force due to hammering affect the piece of iron? The force due to hammering change the shape of the piece of iron. Name the forces acting on a plastic bucket containing water held above ground level in your hand.
Discuss why the forces acting on the bucket do not bring a change in its state of motion.

All the intext and exercise NCERT Solutions for Class 8 questions have been solved in a detailed and step-by-step manner so that students do not face any difficulty in understanding them. Here you will learn what force and pressure are. You will learn the various characteristics of force like force can change the state of motion of an object and its shape, and that it has both magnitude and direction. You will also learn about contact forces muscular force, friction, etc. Lastly, you will learn about pressure — the pressure exerted by liquids and gases and atmospheric pressure.
The chapter will introduce you to the concepts of force.
Сьюзан замерла возле вентиляционного люка. Крик оборвался столь же внезапно, как и раздался. Затем наступила тишина.
Сьюзан на какое-то время забыла про Хейла. Она молила Бога, чтобы Стратмору звонил Дэвид. Скажи мне скорей, что с ним все в порядке, - думала. - Скажи, что он нашел кольцо.
