5.P.1 Understand force, motion and the relationship between them.
- 5.P.1.1Explain how factors such as gravity, friction, and change in mass affect the motion of objects.
- 5.P.1.2Infer the motion of objects in terms of how far they travel in a certain amount of time and the direction in which they travel.
- 5.P.1.3Illustrate the motion of an object using a graph to show change in position over a period of time.
- 5.P.1.4Predict the effect of a given force or a change in mass on the motion of an object.
- 5.P.2.2Compare the weight of an object to the sum of the weight of its parts before and after an interaction.
Vocabulary
acceleration: rate of change in velocity distance:how far an object travels force: any push or pull on an object friction: force that resists motion between two touching surfaces; acts in the opposite direction of the force; can be useful or wasteful inertia: the tendency of an object to resist a change in motion or keep doing what it is doing Note: the greater the mass of an object, the greater the inertia kinetic energy: energy of motion (moving ball going down a ramp) mass: how much matter an object contains momentum: force or speed of movement; mass in motion, example: a moving train has much more than a moving soccer ball motion: an object changing position over time; change in position is measured by distance and time potential energy: stored energy (ball positioned at the top of the ramp) velocity: speed with direction (example: 45 mph northeast) |
