★ SI unit of Force is Newton
What are the Effects of Force?
In physics, motion is defined as the change in position with respect to time. In simpler words, motion refers to the movement of a body. Typically, motion can either be described as:
→Change in speed
→Change in direction
The Force has different effects and here are some of them.
- Force can make a body that is at rest to move.
- It can stop a moving body or slow it down.
- It can accelerate the speed of a moving body.
- It can also change the direction of a moving body along with its shape and size.
Formula for Force
The quantity of force is expressed by the vector product of mass (m) and acceleration (a). The equation or the formula for force can mathematically be expressed in the form of: where,
m = mass
a = acceleration
→ Force formulas are beneficial in finding out the force, mass, acceleration, momentum, velocity in any given problem.
Types of Force
Force is a physical cause that can change the state of motion or the dimensions of an object. There are two types of forces based on their applications:
→ Contact Force
→ Non-Contact Force
