Section 2 What Is a Force?
... Look around the room and think about the objects you see touching another object. A force is always exerted by one object on another object. Answer the following questions on your paper. Where do you see a force happening in the room right now? Which object is exerting the force, and which is receiv ...

... doubled the net force with 40 N. What happens with the acceleration? • If net force doubled, then so is acceleration • Acceleration is directly proportional to the net force. • Acceleration ~ net force Means: Directly proportional • The direction of acceleration is always in the direction of the net ...
