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) |
