Physics
Across
- 2. for every action there is an equal and opposite reaction; In other words, if object A exerts a force on object B, then object B also exerts an equal and opposite force on object A.
- 5. the rate at which speed or direction of a moving object changes
- 7. friction forces caused by air that oppose motion of objects (causing objects to slow down)
- 8. a push or pull on an object
- 10. Describes the relationship between the acceleration of an object, the mass of an object and the force applied to the object; Force equals mass times acceleration.
Down
- 1. a force of attraction between two objects
- 3. An object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force; called the “principle of inertia.”
- 4. the amount of space between two things; measured in length
- 6. A force that resists the motion of an object
- 9. total quantity of an object’s matter
