Practice measuring the period of a pendulum. Perform experiments to determine how mass, length, gravitational acceleration, and angle affect the period of a pendulum.

Measure the period of a mass on the end of a spring. Determine the effects of gravitational acceleration, mass, and the spring constant on the period of the spring. Create an equation for...

Observe two different forms of simple harmonic motion: a pendulum and a spring supporting a mass. Use a stopwatch to measure the period of each device as you adjust the mass hanging from...

Place a pan on the end of a hanging spring. Measure how much the spring stretches when various masses are added to the pan. Create a graph of displacement vs. mass to determine the spring...

Perform experiments with a pendulum to gain an understanding of energy conservation in simple harmonic motion. The mass, length, and gravitational acceleration of the pendulum can be...

Measure the position, velocity, and acceleration (both components and magnitude) of an object undergoing circular motion. The radius and velocity of the object can be controlled, along with...

One of the simplest machines is a see-saw lever. Place up to eight objects on the lever at different locations and try to balance it. Calculate net torque and moment of inertia based on the...

Place masses on a circular table and see how fast it spins when struck by a piston. Discover the relationships between angular velocity, mass, radius and moment of inertia for collections...

Observe and compare objects of different shapes as they roll or slide down an inclined plane. Compare the percentages of translational and rotational kinetic energy for each object, and see...
