Chapter 11: Matter and Motion
Learning Objectives:
11.1 Explain how the Kinetic molecular theory of matter can be used to explain fundamental properties of matter
11.2 Describe distinctive attributes of chemical reactions
11.3 Provide examples for Newton's laws of motion
11.4 Explain how mass and distance relate to gravitational force
Matter is defined as anything that occupies space and has mass. A physical change occurs when matter transitions from one state or phase to another. The kinetic molecular theory is used to explain a wide range of material change.
A chemical change is a change in matter that results in the formation of a new substance. Matter exists in the form of elements, compounds, and mixtures. Atoms are made up of many smaller particles. Matter neither creates nor destroys itself; it simply changes form.
Newton's law of motion describes how the motion of an object changes as forces are applied. Pushes and pulls are examples of forces. Push/ Pulls are made up of two parts: strength and direction. If the pushes and pulls are equal and opposite, there will be no change in motion. A change in motion will occur if they are unbalanced. Changes in speed, direction, or both can be observed.
According to the law of universal gravitation, all masses are attracted to all other masses by a force that varies directly with the mass product and inversely with the square of the distance between them.
That is all for today!
