vocab for science
Across
- 1. the amount of matter in an object and a measure of its resistance to changes in motion (inertia), and it remains constant regardless of location
- 4. a net force that is not equal to zero, meaning the forces acting on an object do not cancel each other out
- 5. the upward force exerted by a fluid (liquid or gas) on an object immersed in it, which resists the object's weight and causes it to float or rise
- 8. the fundamental force of attraction
- 9. a unit of force that will accelerate one kilogram of mass one meter per second squared
- 12. the force that resists the motion of one solid surface sliding over another, acting in the direction opposite to the relative sliding motion between the surfaces
- 13. the single, overall force that results from the combination of all individual forces acting on an object
- 14. the rate at which the velocity of an object changes
- 15. the force that opposes motion between a solid object and a fluid (a liquid or gas), or between layers of a fluid
- 16. a contact force that prevents an object from starting to move across a surface
Down
- 1. a physical property that measures an object's quantity of motion, calculated as its mass multiplied by its velocity
- 2. the pulling force transmitted axially along a flexible connector, like a rope or cable, when it is pulled taut from opposite ends
- 3. a resistance force that opposes the motion of a rolling object, such as a wheel or ball, as it moves along a surface
- 5. two or more forces of equal strength acting in opposite directions
- 6. a push or pull on an object
- 7. a fundamental non-contact force that acts between electrically charged particles
- 10. the resistance of any physical object
- 11. the force of gravity acting on an object's mass
- 17. a push or pull on an object
