Newton's Second Law
Three memorable activities build on each other to give physics masters a firm grasp of Newton's Second Law. Pupils play with a lab cart on a flat surface and on an incline to confirm that force is equal to mass times acceleration. In the...

Spring Scale Engineering
After examining how a spring scale works, teams work together to design their own general measurement device. Reading material provides background information, but there is no part of the procedure in which learners handle an actual...

University of Colorado: Ph Et Interactive Simulations: Masses & Springs
Hang various mass weights on spring scales while you adjust the spring stiffness and damping in this online activity. Slow down the action, take it to another planet, or watch the amount of potential, thermal, and kinetic energy.

Teach Engineering: Sliding and Stuttering
Students use a spring scale to drag an object such as a ceramic coffee cup along a table top or the floor. The spring scale allows them to measure the frictional force that exists between the moving cup and the surface it slides on. By...

Try Engineering: Spring Scale Engineering
Learners learn about the engineering design process as they design, build, and test a spring scale using everyday items that can measure the weight of an apple. The objective of the lesson is to explore how scales work and to learn about...

Walter Fendt: Inclined Plane
This site is an interactive app of an inclined plane showing the effect of the angle, the weight of the block, and the friction as a block is pulled up an incline.
