Understanding Physics Motion and Force
Motion refers to the change of position of an object over time, and force is an interaction that can cause the motion of an object to change. The interaction between these two follows Newton’s Laws of Motion, which describe the influence of forces on movement.
- Newton’s First Law (Law of Inertia): A body at rest stays at rest, and a body in motion continues in motion until an outside force acts on it.
- Newton’s Second Law (Law of Acceleration): The force on an object is equal to its mass (m) times acceleration (a)(F=ma).
- Newton’s Third Law (Action-Reaction): For every action, there is an equal and opposite reaction.
Now for the strengthening of your concept here are some MCQs with answers regarding Physics Motion and Force.
