To investigate Newton's laws of motion.
A light object will have greater acceleration compared to a heavy object given that the force is constant. .
2. If an object with velocity collides into a stationary object, if the two objects have the same mass, then both objects will continue moving at half the velocity of the accelerating object before the collision.
Introduction .
Sir Isaac Newton in presented his three laws of motion in the "Principia Mathematica Philosophiae Naturalis" which was published in 1687. Newton's laws of motion shaped our understandings of the universe today, and are rather simple to understand, because they are intuitive and thus instinctive to the average human. .
Newton's 3 laws of motion:.
1. "An object at rest will remain this way unless it is acted upon by a force" (Greenwood et al, 2012) and "an object that is moving will continue to move at the same speed and in the same direction unless an unbalanced force acts upon it." (Greenwood et al, 2012) This is known as the law of inertia. .
2. "An object will accelerate in the direction of an unbalanced force acting upon it. The size of this acceleration depends upon the mass of the object and the size of the force acting" (Greenwood et al, 2012). This can also be expressed as F= ma (force is equal to mass times acceleration).
3. "For every action force there is an equal and opposite reaction force" (Greenwood et al, 2012).
There are many different types of forces, but the most commonly known forces are friction and gravity. .
Newton's second law states that F= ma, where F stands for force. It is important to consider that force has both magnitude and direction, making it a vector quantity and not a scalar quantity. A scalar quantity will only have size, but not direction. A good example of these two quantities are distance and displacement. Distance is a scalar quantity because it only states the distance travelled (e.
