Force and Motion

What is the general relationship between the mass applied and the extension on the spring?

• (1) a direct relationship: as mass increases, the extension of the spring increases

• (2) an indirect relationship: as mass increases, the extension of the spring decreases

• (3) constant relationship: as mass increases, the extension of the spring stays the same

• (4) no relationship: there is no relationship between the mass and the extension of the spring

Based on the data, estimate the extension of the spring when a 450-gram mass is applied.

• (1) 0.2 cm

• (2) 0.7 cm

• (3) 0.9 cm

• (4) 2.0 cm

The arrows in the diagram below represent the forces acting on a moving bicycle at two different times, time 1 and time 2. The length of each arrow represents the amount of force being applied.  As a result of the change in the forces from time 1 to time 2, the bicyclist will

• (1) move slower in a forward direction

• (2) move in a backward direction

• (3) move faster in a forward direction

• (4) stop moving

The diagram below represents a roller coaster at two positions on the roller coaster track. Compared to the potential energy of the roller coaster at the top of hill 1, the potential energy of the roller coaster at the top of hill 2 is

• (1) less because the roller coaster is at a lower elevation

• (2) less because the roller coaster is on a more gentle slope

• (3) greater because the roller coaster is at a lower elevation

• (4) greater because the roller coaster is on a more gentle slope
