Example: Using force to push or pull a door.
The SI power unit of Force is Newton(N).
Laws of Motion
To scientifically e plain ho things mo e a scientist named saac e ton de eloped three a s o
Motion.
l First Law of Motion
According to the first law, an object will remain at
rest or in uniform motion in a straight line unless
force is applied on an object to change its state.
That implies that the ball will continue to be at rest
until an external force is applied to push it.
l Second Law of Motion
According to the second law, the acceleration of an
object depends on the mass of the object and the
amount of force applied.
In fact, the formula
Force = mass x acceleration
or F=ma
states that force is equal to mass times acceleration. This also implies that a ball will travel farther
the harder you kick it.
l Third Law of Motion
According to the third law, every action has an equal and
opposite reaction. This implies that there are always two
identical forces acting on one another. In the case when
you kick the ball, the force that your foot exerts on it is
equal to the force that the ball exerts on your foot. This
force is acting completely in the opposite manner.
Program to Calculate the Force
To create an AI Connect program to calculate the force, create a project. In this project create a
Basic Coding activity. Then follow the given steps:
Here, we take an example of a car of mass 1500 Kg that accelerates at 2 m/s.
Step 1 Declare two variables mass and acceleration to store the value of mass and acceleration
respectively of the car.
