Force is the correct answer.
Explanation:
- Definition of force: In physics, force is defined as an external influence that changes or tends to change the state of rest or uniform motion of a body or its dimensions.
- Effects of force: Force can cause a stationary object to start moving, stop a moving object, change the direction of motion of an object, or change the shape or size of an object.
- Types of forces: There are various types of forces, such as gravitational force, electromagnetic force, frictional force, applied force, normal force, etc. These forces can act on an object independently or simultaneously.
- Force and motion: Force is responsible for any change in the motion of an object. If there is no force acting on an object, it will remain at rest or continue to move with a constant velocity (if no other forces are acting on it). However, if a force is applied to an object, it will accelerate or decelerate depending on the direction and magnitude of the force.
- Force and dimensions: Force can also change the dimensions of an object. For example, when a force is applied to stretch or compress a spring, its length changes. Similarly, when a force is applied to deform a rubber ball, its shape changes temporarily.
- Measurement of force: The SI unit of force is the Newton (N). A force of 1 Newton is defined as the force required to accelerate a mass of 1 kilogram at a rate of 1 meter per second squared.
- Force and equilibrium: When forces acting on an object are balanced, the object is in a state of equilibrium, either at rest or in uniform motion. However, if the forces are unbalanced, the object will accelerate in the direction of the net force.
- Importance of force: Force is a fundamental concept in physics and is used to explain various phenomena in the natural world. It plays a crucial role in understanding the motion, behavior, and interactions of objects in the universe.
Therefore, force is the external influence that can change or tend to change the state of rest or uniform motion of a body or its dimensions.
