Basic of Physics includes the Force and motion with Formulas and the Units. Basic Physics also explains the types of Force and Motion. Here we can also explain about the relationships of the motion with Newton’s second law of motion and the force of momentum, etc.
What is Force?
Force is a physical quantity that can change the motion or direction of a body. When a force is applied to a body, that body can speed up, slow down, stop, or change direction. Without a force, a body cannot move or change its motion.
Example of force: When you push a door, you are applying a force to it to make it move. If you push harder, the door will open faster. Explanation: Your hand is applying a force to the door to change its state of rest into motion.
Formula of Force: When we know the mass of an object and the acceleration it produces, we calculate force as follows:
Force=Mass×Speed
Force = m × a
m = Mass (in kilograms)
a = Speed (in meters per second squared)
SI Unit of Force: The International Unit (SI Unit) of force is the Newton (N). 1 Newton = the force that gives a 1 kilogram body an acceleration of 1 meter per second squared.
What is Motion?
Motion is a physical state in which a body changes its position over time. When a body changes its position relative to a starting point, it is said to be in motion.
Example of Motion: For example, if a car is moving down the road, it is moving because it is changing its location over time.
SI Unit of Motion: Motion does not have a specific SI unit, but is measured in units such as meter (m), meter/second (m/s), or meter/second² (m/s²), which are for distance, velocity, and acceleration.
Formula of Force: velocity=displacement / Time
