Physics Lab Video: Wave Motion
Wave motion is an important method of transferring energy from one place to another
without involving the actual transfer of matter. When a pebble is dropped into a still pool, some

Heat is a very curious from of energy. It helps us stay warm, prepare hot and tasty food
but its applications far exceed the domestic uses mentioned. Understanding the properties of he

1. A golf club exerts an average force of 1000 N on a 0.045-kg golf ball which is initially at rest. The
club is in contact with the ball for 1.8 ms. What is the speed of the golf ball as it leaves the tee?

Addition of Vectors
Purpose: In this lab, we check a special case of Newtons laws, namely that the sum of
the forces acting on an object in equilibrium is zero. Since forces are vectors, we will
practice doing vector additions.
First, we measure
