In Physics, force is defined as: The push or pull on an object with mass causes it to change its velocity. Force is an external agent capable of changing a body’s state of rest or motion. It has a magnitude and a direction.

t. e. In physics, a force is an influence that can cause an object to change its velocity, i.e., to accelerate, meaning a change in speed or direction, unless counterbalanced by other forces. The concept of force makes the everyday notion of pushing or pulling mathematically precise.

Updated on January 10, 2020. In science, force is the push or pull on an object with mass that causes it to change velocity (to accelerate). Force represents as a vector, which means it has both magnitude and direction. In equations and diagrams, a force is usually denoted by the symbol F.
Sep 12, 2022 · Understand the definition of force. Identify simple free-body diagrams. Define the SI unit of force, the newton. Describe force as a vector. The study of motion is called kinematics, but kinematics only describes the way objects move—their velocity and their acceleration.
We know that a push or a pull has both magnitude and direction (therefore, it is a vector quantity), so we can define force as the push or pull on an object with a specific magnitude and direction. Force can be represented by vectors or expressed as a multiple of a standard force.
We discuss further details about net force, external force, and net external force in the coming sections. Like displacements, velocities, and accelerations, forces are vectors that have magnitude and direction.
The word force can take on different meanings—how is it used in science? Learn about what a force is and how a Isaac Newton's Laws of Motion changed the world's view of how forces and motion work.
