Force Sensor Light Gate attached to the track
Dynamics cart with interrupt card and crumple zone attached
Force sensor with an extension target attached
An extension target can be attached to the Force sensor to increase its frontal surface area. E.g. Cut a rectangle of 6 mm plywood (or equivalent), 11 x 4 cm in size and drill a 5 - 6 mm hole in the centre. Cut two more pieces of wood 4.6 x 4 cm in size and glue to the ends of the rectangle. Use the solid safety stop to attach the target to the centre hole in the base of the Force Sensor.
Two Force sensors can be used to measure the forces generated when a moving object collides with another object. E.g. Newton’s 3rd Law – Action and Reaction
