Force and motion are interconnected. Here is a detailed explanation of both the terms with example.
A force is pushing or pulling action that can make things move, change direction, or change shape. When a force acts on an object, it often makes it move faster or in a different direction.
- The Earth’s gravity causes everything on Earth to have weight. Gravity is a force that pulls everything toward the centre of the Earth. Gravity is holding both the pebble and the boulder down while you are trying to throw them. Gravity is a force acting against your force.
- The unit of force is the Newton (N), and a force of 1 N is defined as the force that, when applied to an object with a mass of 1 kg, produces an acceleration of 1 m/s2. If we apply a force equal to 2 N, the corresponding acceleration is 2 m/s2.
- A force acting on an object produces an acceleration. The direction of the acceleration is the same as the direction of the force applied.
Motion means moving something from one place to another. When you used force to swing the bat and hit the baseball, they moved from one place to another.
- The motion requires force to cause that change.
- Everybody maintains its initial state of rest or motion with uniform speed on a straight line unless an external force acts. This law is also known as the law of Galileo or the law of inertia.
Force and motion
Suppose something is moving; we can say that some force must be acting on it or some force must have acted on it, which produced this motion. If a person is walking, and hence in motion, there must be some force acting on it to make his move. By definition itself, it is clear that force affects the state of motion of an object.
