Newton's laws of motion are three physical laws that form the basis for classical mechanics, directly relating the forces acting on a body to the motion of the body.
There exists a set of inertial reference frames relative to which all particles with no net force acting on them will move without change in their velocity. This law is often simplified as "A body persists its state of rest or of uniform motion unless acted upon by an external unbalanced force." Newton's first law is often referred to as the law of inertia.
Second law Observed from an inertial reference frame, the net force on a particle of constant mass is proportional to the time rate of change of its linear momentum:
F = d(mv)/dt. This law is often stated as, "Force equals mass times acceleration (F = ma): the net force on an object is equal to the mass of the object multiplied by its acceleration.
Whenever a particle A exerts a force on another particle B, B simultaneously exerts a force on A with the same magnitude in the opposite direction The strong form of the law further postulates that these two forces act along the same line. This law is often simplified into the sentence, "To every action there is an equal and opposite reaction.”
How to use:
1. Put the weights on the holder as much as the test requires.
2. If the test requires driving force, connect with springs or rubber band.
3. If the test requires several carts, connect with front and rear magnets.
