Newton's first law of motion - sometimes referred to as the law of inertia. An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force
An unbalanced force causes an object to accelerate. The acceleration of the object is equal to the net force acting on it divided by the object's mass. If you use the same force to push a truck and push a car, the car will have more acceleration than the truck, because the car has less mass.
Newton's second law of motion can be formally stated as follows: The acceleration of an object as produced by a net force is directly proportional to the magnitude of the net force, in the same direction as the net force, and inversely proportional to the mass of the object.According to Newton, an object will only accelerate if there is net or unbalanced force acting upon it. The presence of an unbalanced force will accelerate an object - changing its speed, its direction, or both its speed and direction.
A force is a push or a pull that acts upon an object as a results of its interaction with another object. For every action, there is an equal and opposite reaction. The statement means that in every interaction, there is a pair of forces acting on the two interacting objects. The size of the forces on the first object equals the size of the force on the second object.
If an object A exerts a force on object B, then object B must exert a force of equal magnitude and opposite direction back on object A.
