Placing the Fulcrum on a Seesaw
A 200.0 g mass is placed at the 20.0 cm mark on a uniform 93 g meterstick. A 100.0 g mass is placed at the 90.0 cm mark. Where on the meterstick should the fulcrum be placed to balance the system?

What is a radian
👉 Learn about angles in trigonometry. An angle is the figure formed by two rays sharing the same endpoint. The two rays are called the sides of the angle while the common endpoint of the two rays is called the vertex of the angle. Angle...

Rotations in the Coordinate Plane
In this video lesson we will learn how to rotate figures in the coordinate plane about the origin. We will understand that all rotations result an image that is congruent to the original figure. The origin will be the center of rotation....
