HS, Physical Science Std 7.1: Solve problems for velocity, acceleration, force, work, and power. • Calculate velocity, acceleration, force, work, and power. • Interpreting graphical representations of velocity versus time and distance versus time • Determining the resultant of collinear forces acting on a body • Describing action and reaction forces, inertia, acceleration, momentum, and friction in terms of Newton’s three laws of motion.

Lesson Plans: Kinetic Energy and Work The main objective of this Mini-teach is for students to observe kinetic energy in balls of the same size but of different mass. Demonstrating The Kinds of Energy To develop a theory of molecular motion that explains the behavior of gases both qualitatively and quantitatively. WORK, POWER AND ENTROPY To demonstrate, explain and allow the student to experience work and power. What Is Work? To show work (w) equals force (f) times distance (d) and the connection between work and potential energy, kinetic energy, and heat. Acceleration To develop an understanding of velocity and to distinguish it from speed. To learn to determine the difference between a scalar and a vector quantity. To learn how acceleration is derived from velocity and time. Action and Reaction To demonstrate that forces occur only in pairs. Straight Line Motion in Two Parts Students will observe both constant and accelerated (changing) motion. They should be able to calculate speed from distance and time measurements. Straight Line Motion in Two Parts Students will observe both constant and accelerated (changing) motion. They should be able to calculate speed from distance and time measurements. They will graph distance vs. time for each motion and observe that the two motions look different when graphed. Acceleration of a Cart Analyze the motion of an accelerating cart. Sports in Physics: Measuring Velocity in a Mini-Olympics To demonstrate an understanding of the difference between speed, velocity, and acceleration. Softball Toss Using time, distance, g, and vector analysis, determine velocity of ball thrown into air. Vector Addition Determine the weight of an object by vector analysis.
