NCERT Solutions for Class 8 Chapter 1 Force and Pressure


A force can be a push or a pull. When a force is exerted on an object, it can change the object's speed, the direction of movement or shape. The pressure is a measure of how much force is acting upon an area. Pressure can be found using the equation pressure = force/area. The magnitude commonly expresses the strength of a force. Suppose the force is applied in the direction opposite to the direction of motion. Then it results in a decrease in the speed of the object.
