Mechanics—Momentum and Collisions,

Ballistic Pendulum, Economy Choice
Effectively demonstrate the conservation of momentum, calculate the initial velocity
of a projectile, or determine the potential energy of a spring. Shoot the ball into
a pendulum bob to inelastically capture it. The ball and bob swing to a maximum
angle that is registered by a light-weight, counterbalanced pointer. Using the mass
of the ball and bob, the maximum angle, and their knowledge of the conservation of
momentum, students calculate the initial “muzzle” velocity of the ball. Repeatable,
accurate results are achieved quickly and easily. Detailed instructions are included.

Collider
Three demonstrations in one! In the first activity, the ramps’ distinctive “equal-time”
cycloid curve guarantees that the balls will collide when they are released at the
same time, regardless of their initial heights. Next, flip the ramps over and release
the balls simultaneously from the top of the straight ramps. Arrival at the bottom of
the ramps is “announced” when the balls strike a chime. By varying the height of the
two launched balls, each ball will have a different arrival time. Repeat the experiment
with the cycloidal ramps to obtain vastly different results! Finally, compare the
motion of one ball on the straight ramp to the other on the cycloidal ramp. Students
will clearly observe that the shortest distance between two points is not necessarily
the fastest! Includes two 1⁄2" steel balls and two 3⁄4" steel balls, chime bar, carbon
paper and detailed instructions.

AP10540 Discovering STEM—Newton’s Laws $37.05
Collision in Two Dimensions
Study the conservation of momentum and the conservation of energy in collisions.
Demonstrate the differences between elastic and inelastic collisions. The Collision
in Two Dimensions apparatus works by holding a steel ball at the top of a curved
aluminum track. When the ball is released, it travels down the track and collides with
another ball placed on an adjustable target support. Students then observe how the
two balls fall. Supplied with track, two steel balls, a hollow wooden ball, and a plumb
bob. Complete instructions provided.

Newtonian Demonstrator
This classic demonstrator is perfect for illustrating Newton’s laws of motion and the
conservation of momentum. The large swinging balls can be manually aligned to
produce nearly perfect elastic collisions. High-quality wooden construction will last
for years. Measures 7" x 9" x 81/2" tall.

Newtonian Demonstrator, Economy Choice
Demonstrate that for every action there is an equal and opposite reaction. Lift and
drop one ball to see one ball pop out from the other side. Lift two balls and two pop
out.
