Action and reaction forces act on different bodies, so they do not cancel each other out. Since they act on separate objects, they can cause motion, as seen when a swimmer pushes water backward and moves forward.

Newton’s second law states that force is equal to the rate of change of momentum (F = ma). If no external force acts on a body (F = 0), then acceleration (a) is also zero. This means the object remains at rest or in uniform motion, which is Newton’s first law. Related Questions: When a … Read more
Applying brakes only on the front wheel causes a sudden stop, while the rider’s inertia keeps them moving forward, increasing the risk of being thrown over the handlebars. It is safer to apply brakes on both wheels for balanced stopping. Related Questions: When a motorcyclist hits a stationary car, he may fly off the motorcycle, … Read more
When the branch is shaken, it moves, but the leaves tend to stay in their original position due to inertia. This difference in motion causes the leaves to detach and fall.

When the motorcycle stops suddenly due to the collision, the motorcyclist continues moving forward due to inertia, causing him to fly off. Similarly, the car driver’s head snaps backward or forward because their body is attached to the seat, but their head remains in motion, leading to whiplash injuries.

Ans: Due to the vast scope and research in physics, it is usually divided into several branches some of them given below: Mechanics: Description: Motion of objects and how it relates to forces. Examples: falling objects, friction, weight, spinning objects Heat and Thermodynamics: Description: Heat and temperature their related to energy. Examples: melting and freezing … Read more
Ans: Physics: ‘Physics can be defined as the study of matter and energy’. Physics and Technology: Rockets and space shuttles, magnetically levitating trains, and microscopic robots that fight cancer cells in our bodies. All of these technologies, whether ordinary or exciting, are based on the principles of physics. Physics is behind every technology and plays … Read more
