Mousetrap Cars

What is a lever?

• A type of pulley used to lift heavy objects.

• A beam that pivots about a fixed hinge, or fulcrum.

• A tool used for measuring angles.

• A device that converts linear motion into rotational motion.

What industry did society transition to during the Industrial Revolution?

• Agricultural industry

• Machine-based industry

What is the relationship between force and motion in a mousetrap car?

• The mousetrap car moves due to the force applied by the mousetrap, illustrating Newton's laws of motion.

• The mousetrap car does not move unless an external force is applied.

• The motion of the mousetrap car is independent of the force applied by the mousetrap.

• The mousetrap car moves in a circular motion due to the force applied by the mousetrap.
