A force which acts at the surface of contact, when one body moves or tends to move upon another body is called the force of friction. Force is pushing or pulling any object resulting from the object’s interaction with another object. To observe the attraction and repulsion between two magnets. It is an opposing force that opposes the motion of one body over the surface of another body. It is a quantitative interaction between two physical bodies, between an object and its environment. The force exerted by magnets on each other and metals like iron and nickel is magnetic force. Force is a physical cause that can change the state of motion or the dimensions of an object. Forces which can act without being in contact with object are called non contact forces. Material required: A pair of bar magnet, three round shaped pencils. It is seen that a soon as the end of the bar magnet comes closer to the common pins, they are pulled towards magnet. What Is Black Hole? We serve courses for different educational boards like CBSE, Maharashtra, Karnataka, Madhya Pradesh, Telangana, Andhra Pradesh, Tamilnadu, Kerala, Assam, Goa, Sikkim, Nagaland, Uttar Pradesh, Madhya Pradesh, Bihar, Haryana, Punjab, Uttarakhand, Jammu & Kashmir, Jharkhand educational boards. We see that the magnet on the pencil goes away i.e., it experience a force of repulsion (like poles repel each other). When we lift, push, pull, stretch or compress something, we use our muscular force. For a body moving downward, g is taken as positive while for a body moving upward, g is taken as negative. Thus, resultant force = (400 N − 300 N) = 100 N and will act in the direction in which A is pulling. Online Test for Class 8 Physics Force and Pressure . Thus, the force (pull) causes stretching in the rubber tube. These references are copyright of NCERT and we are only a medium to convey its reach among large number of students easily.

For example, if a book slides across the surface of a desk, then the desk exerts a friction force in the opposite direction of its motion. It consists of a coiled spring which gets stretched when a force is applied to it. Suppose a body is placed on the table following three forces act on it: Body is not moving, so all the forces must be balanced, normal force by table and force by earth balanced each other, to balance the applied force there must be an equal and opposite force, this force is known as force of friction.
