Forces and Motion

Newton's Cradle

Program of Studies

SC-7-MF-S-1 – Students will use appropriate tools and technology (e.g., timer, meter stick, balance, spring scale) to investigate the position, speed and motion of objects

SC-7-MF-S-2 – Students will test the cause and effect relationship between straight-line motion and unbalanced forces

SC-7-MF-S-3 – Students will investigate balanced and unbalanced forces and their effect on objects and their motion

SC-7-MF-S-4 – Students will make inferences and draw conclusions about the motion of objects, and predict changes in position and motion as related to the mass or force

SC-7-MF-S-5 – Students will calculate work as the product of force and distance moved in the direction of the force

SC-7-MF-S-6 – Students will identify gravity as a force that acts over a distance, and distinguish it from other forces that do the same (e.g. magnetism)

SC-7-MF-S-7 – Students will investigate the properties of gravity and observe its effects on objects

SC-7-MF-S-8 – Students will distinguish between weight (as a function of gravity) and mass (matter content) of an object

Core Content

SC-07-1.2.1 – Students will explain the cause and effect relationship between simple observable motion and unbalanced forces.

An object remains at rest or maintains a constant speed and direction of motion unless an unbalanced force acts on it (e.g., gravity). When an unbalanced force acts on an object, the change in speed or direction depends on the size and direction of the force.
