Forces and Motion

  • Predict, qualitatively, how an external force will affect the speed and direction of an object's motion.
  • Explain the effects with the help of a free body diagram.
  • Use free body diagrams to draw position, velocity, acceleration and force graphs and vice versa.
  • Explain how the graphs relate to one another.
  • Given a scenario or a graph, sketch all four graphs.

Forces and Newton's Laws of Motion

saac Newton (1642–1727) was a natural philosopher; a great thinker who combined science and philosophy to try to explain the workings of nature on Earth and in the universe. His laws of motion were just one part of the monumental work that has made him legendary. The development of Newton’s laws marks the transition from the Renaissance period of history to the modern era. This transition was characterized by a revolutionary change in the way people thought about the physical universe. Drawing upon earlier work by scientists Galileo Galilei and Johannes Kepler, Newton’s laws of motion allowed motion on Earth and in space to be predicted mathematically.

Friction

  • Describe a model for friction a molecular level.
  • Describe matter in terms of molecular motion. The description should include: diagrams to support the description, how the temperature affects the image, what are the differences and similarities between solid, liquid and gas particle motion; how the size and speed of gas molecules relate to everyday objects.

Intro to vectors and scalars

Scalars and vectors are two kinds of quantities that are used in physics and math. Scalars are quantities that only have magnitude (or size), while vectors have both magnitude and direction. Explore some examples of scalars and vectors, including distance, displacement, speed, and velocity.

Introduction to energy

Energy is defined as the ability to do work. Energy can be found in many things and can take different forms. For example, kinetic energy is the energy of motion, and potential energy is energy due to an object's position or structure. Energy is never lost, but it can be converted from one form to another.
