Science vocabulary

3. a push or a pull on an object.
4. diagram,
6. the speed and the direction of a moving object.
7. a region of space that has a physical quantity (such as a force) at every point.
9. the gravitational force exerted on an object.
12. force, a force that one object applies to another object without touching it.
16. the difference between the initial, or starting, position and the final position.
17. contact force that resists the sliding motion of two surfaces that are touching.
19. an object’s distance and direction from a reference point.
20. the process of changing position.
22. force, the force that pushes perpendicular to the object’s surface.
23. collision, when colliding objects bounce off each other.

1. a measure of the change in velocity during a period of time.
2. force, a push or a pull on one object by another object that is touching it.
5. point, the starting point you choose to describe the location, or position, of an object.
8. first law of motion, an object at rest will stay at rest, and an object in motion will stay in motion unless a force acts on the object.
10. an attractive force that exists between all objects that have mass.
11. pair, the forces two objects apply to each other.
12. force, the combination of all the forces acting on an object.
13. a measure of the distance an object travels in a given amount of time.
14. second law of motion,
15. a quantity that has both magnitude and direction.
18. third law of motion, when an object applies a force on another object, the second object applies a force of the same strength on the first object but the force is in the opposite direction.
21. that states that the acceleration of an object is equal to the net force exerted on the object divided by the object’s mass.
