8. Physics Vocabulary force:a push or a pull net force: the combination of all the forces acting on an objectgravity: an attractive force that exists between all objects that have forcevelocity: the change in an object’s position over time; includes both speed and directionacceleration: the change in an object’s velocity over timeinertia: the tendency of a moving object to keep moving, or a nonmoving object to stay at restfriction: the rubbing force that opposes motion speed: a measure of how far an object moves in a certain amount of timeinertia: the tendency of a moving object to keep moving, or a nonmoving object to stay at restNewton’s first law of motion: the physical law stating that objects do not change their motion unless a force is applied to them; also known as Newton’s law of inertiaNewton’s second law of motion: the physical law stating that the net force F on an object equals the product of the object’s mass m and acceleration a:F = maNewton’s third law of motion: the physical law stating that for every action force, there is an equal and opposite reaction force

10. Forces • Name some types of forces.

11. Forces are shown by arrows. • The arrows often show the direction and amount of force. • A force is a push or a pull • Force is measured in Newtons.

12. Balanced and Unbalanced Forces • Use a toy car to determine how an object behaves when a forces are applied. • Use an arrow to illustrate the forces applied

13. Balanced Forces Balanced Forces Unbalanced Forces Unbalanced Forces Balanced Forces Balanced Forces Unbalanced Forces Unbalanced Forces
