Task 3 : Newton's 1st, 2nd and 3rd law of motion.
Explain Newton's 1st law, 2nd Law and 3rd Law of motion, with 1 example for each. NEWTON'S 1ST LAW OF MOTION. Newton's first law of motion was discovered by Sir Isaac Newton. It states about the inertial nature of an object. Newton's first law of motion states that an object will remain in its original state or in a state of uniform velocity if no external force acts on the object. An object that is stationary will remain stationary. For example, a stone in the ground is in a state of rest. The rock will remain stationary on the ground when no force is applied. Therefore, to move the stationary object, an external force is required. The stationary stone moves when a force (throwing a stone) is applied to it. When an object moving with uniform velocity it will keep moving with uniform velocity along a straight line . To change that condition, an external force must be acted on the object. NEWTON'S 2ND LAW OF MOTION Newton's second law of motion states
