Momentum and Collisions (Part 3)

What You'll Learn

Momentum is mass times velocity. A heavy truck moving slowly can have the same momentum as a light car moving fast. Momentum is conserved in collisions.

Key Words

kinetic
potential

Materials Needed

marbles
paper clips
rubber bands
blocks

Safety First

Dispose of materials properly after the experiment.
Handle glass items carefully to avoid breakage.

Steps

Step 2 — Do

Compare your results with a partner.

Step 3 — Observe

Watch carefully for any changes and note the time.

Step 4 — Record

Create a data table to organize your measurements.
