FORCES AND MOTION: GRAVITY, FRICTION & MASS
(NCDPI 5th Grade Science Unpacking Documents: PDF)
5.P.1 Understand force, motion and the relationship between them.
5.P.1.1 Explain how factors such as gravity, friction, and change in mass affect the motion of objects.
- Students know that gravity pulls any object on or near the earth toward it without touching it.
- Students know that friction is a force that is created anytime two surfaces move or try to move across each other.
- Students know that all matter has mass.
- Students understand that changing any or all of these factors will affect the motion of an object.
5.P.1.2 Infer the motion of objects in terms of how far they travel in a certain amount of time and the direction in which they travel.
- Students know that it is possible to measure the motion of an object based on the distance it will travel in a certain amount of time.
5.P.1.3 Illustrate the motion of an object using a graph to show a change in position over a period of time.
- Students know that a graph can be created using one axis to represent the distance that an object travels, and the other axis to represent the period of time the object is traveling.
- Students know how to construct a graph that demonstrates a relation of distance to time.
5.P.1.4 Predict the effect of a given force or a change in mass on the motion of an object.
- Students know that the greater a force is, the greater the change (in motion) it produces. The greater the mass of the object being acted on, the less the effect of the (same) force.
