Product Details

Demonstrate the relationship between angular velocity and centripetal acceleration. The low cost and simple construction of the centripetal force apparatus make it a must for every classroom. The experiment uses the weight of 20 washers hanging from one end of a nylon thread to balance the pull of a rubber stopper swinging overhead. Complete instructions provided.


Materials Included in Kit: 
Acrylic hollow handle, 5"
Paper clip, jumbo, 2", 2
Pulley cord, 2 yd
Stopper, black, rubber, 2-hole, size #4
Washers, ⅜" i.d. x 1" o.d. x 5/64", 20

Performance Expectations

MS-PS2-1: Apply Newton’s Third Law to design a solution to a problem involving the motion of two colliding objects.
MS-PS2-2: Plan an investigation to provide evidence that the change in an object’s motion depends on the sum of the forces on the object and the mass of the object
MS-PS2-4: Construct and present arguments using evidence to support the claim that gravitational interactions are attractive and depend on the masses of interacting objects
MS-PS3-1: Construct and interpret graphical displays of data to describe the relationships of kinetic energy to the mass of an object and to the speed of an object.
HS-PS2-1: Analyze data to support the claim that Newton’s second law of motion describes the mathematical relationship among the net force on a macroscopic object, its mass, and its acceleration.
HS-PS2-4: Use mathematical representations of Newton’s Law of Gravitation and Coulomb’s Law to describe and predict the gravitational and electrostatic forces between objects.
