U15014 Set of six steel balls

3/03 ALF

Steel balls suitable for experiments on elastic and inelas-

tic collisions on a slide rail.

1. Description, technical data

Set of 6 hardened and polished steel ball bearings.

Diameter: 30 mm each

Weight: 110 g each

2. Instructions for use

• Experiment is set up on a metal slide rail (e. g. U17150)

or using 2 stands (U15004) on stand components.

• Track or stands should be adjusted to the horizontal

using a spirit level. Fine adjustment can be achieved

using the screws on the stand base.

2.1 Elastic collisions

• Roll one ball with various degrees of strength against

another stationary ball.

• Observe the speeds of the balls before and after

impact. (The stationary ball moves away at the same

speed while the impacting ball comes to rest. Mo-

mentum is transferred completely from one ball to

the other.)

2.2 Inelastic collisions

• Attach sticky tape to a stationary ball to ensure that

a collision will be inelastic.

• Roll one ball with various degrees of strength against

the stationary ball.

• Observe the speeds of the balls before and after

impact. (After impact, both balls move at approxi-

mately half the original speed of the impacting ball

before the collision.)

2.3 Several balls

• Roll one ball into 5 other balls that are touching one

another.

• Observe the speed of all the balls after an elastic

collision.

• Repeat the experiment with 2 (3) balls rolling one

behind the other into 4(3) stationary balls that are

touching one another.
