An applied force, exerted by one object on another, modifies the physical state of the recipient object. It alters the object’s motion, either by changing its velocity or direction, or by causing it to change shape or orientation. The force applied can be either a contact force, like friction or tension, or a non-contact force, such as gravity or magnetism.
What is an Applied Force?
Applied force is the exertion of effort that causes an object to move or change its motion. This force may be applied in any direction, whether it’s pushing, pulling, twisting, or lifting. Understanding the concept of applied force is crucial in various fields, including physics, engineering, and everyday life situations.
Characteristics of Applied Force:
- Force is a vector quantity, meaning it has both magnitude (strength) and direction.
- Applied force can alter an object’s speed, direction, or both.
- It can be applied by humans, machines, or even natural phenomena like gravity.
- The amount of force applied is directly proportional to the mass and acceleration of the object.
Types of Applied Forces:
-
Contact Forces:
- Require physical contact between two objects.
Examples:- Pushing a door
- Friction between tires and road
- Require physical contact between two objects.
-
Non-Contact Forces:
- Act over a distance without physical contact.
Examples:- Gravity
- Magnetic forces
- Act over a distance without physical contact.
Effects of Applied Force:
- Linear Motion: Applied force can cause an object to move in a straight line, either accelerating or decelerating.
- Rotational Motion: Force applied at a distance from an object’s center can cause it to rotate.
- Deformation: Force can also cause objects to deform, depending on the magnitude and direction of the force.
Applications of Applied Force:
Applied force finds applications in numerous fields:
- Engineering: Designing structures and machines
- Sports: Generating power and momentum
- Medicine: Treating injuries and performing surgeries
- Transportation: Propelling vehicles
- Everyday Life: Performing tasks like opening doors or lifting objects
Question 1: What is meant by an applied force?
Answer: An applied force is an influence that causes an object to undergo a change in motion or deformation. The applied force is typically exerted by an external agent, such as a human pushing or pulling on an object, or a machine applying a force to an object.
Question 2: How does an applied force affect an object?
Answer: An applied force can cause an object to accelerate, decelerate, or change direction. The magnitude of the applied force determines the amount of acceleration or deceleration experienced by the object, while the direction of the force determines the direction of the change in motion.
Question 3: What is the difference between an applied force and a reactive force?
Answer: An applied force is an external force that is applied to an object by an outside agent, whereas a reactive force is an internal force that is generated within the object in response to the applied force. Reactive forces always oppose the applied forces and have the same magnitude but opposite direction.
And there you have it, folks! Now you know what an applied force is. It’s basically any force that’s applied to an object by something else. When you push a door open, you’re applying a force to it. When you kick a ball, you’re applying a force to it. And when you’re sitting in your chair reading this article, the force of gravity is pulling you down to the Earth.
