Students visualize the relation between acceleration and velocity in 2 dimensions. They are introduced to Newton's first law,and Newton's second law. Students work on an exploration activity where they condsider an example of a...

Eighth graders differentiate speed and velocity. In this physics lesson, 8th graders explain Newton's laws of motion. They calculate speed using a mathematical formula.

Students describe how cosmic rays achieve high kinetic energy via conservation of momentum.

Learners explore types of motion. For this motion experiment, students observe how objects move. Learners work in small groups to discover the laws of motion.
