Chapter 4: Forces and the Laws of Motion

Newton’s Laws of Motion

Newton’s Laws On-Board the International Space Station. This video provides a primer on the laws of motion and includes demonstrations of certain principles by Daniel M. Tani, an astronaut onboard the ISS.

(Objective: Explain the relationship between the motion of an object and the net external force acting on the object.)

 

This game uses an apple and worm in various situations to explain Newton’s Laws of Motion. You may feel some sympathy for the worm. Test your knowledge after the game with a quiz and read a short biography of Newton.

(Objective: Describe an object’s acceleration in terms of its mass and the net force acting on it; Predict the direction and magnitude of the acceleration caused by a known net force.)
