Across
- 3. of force and acceleration – Newton’s 2nd law; when a force acts upon an object that has a constant mass, the object will accelerate in the same direction as the force applied
- 4. – change in an object’s motion (speed and/or direction); caused by unbalanced forces; measured in m/s2
- 6. – a measure of the amount of matter in a sample
- 8. the resistance that one surface or object encounters when moving over another
- 9. forces - a situation where the forces acting on an object are not equal in magnitude or direction, resulting in a net force that is not zero, causing the object to change its state of motion (accelerate, speed up, slow down, or change direction)
- 13. of inertia – Newton’s 1st law; the tendency of an object to resist change in motion unless acted upon by an outside net force
- 14. the rate at which someone or something is able to move or operate.
Down
- 1. at the same time.
- 2. the SI unit of force. It is equal to the force that would give a mass of one kilogram an acceleration of one meter per second per second and is equivalent to 100,000 dynes.
- 5. - the force that attracts a body toward the center of the earth
- 7. – a push or pull acting on an object
- 10. forces- when two or more forces acting on an object are equal in magnitude but opposite in direction, effectively canceling each other out and resulting in no net force
- 11. of action-reaction – Newton’s 3rd law; for every action, there is an equal and opposite reaction
- 12. force – measurement of the total forces exerted on an object; measured in Newtons (N)
