Across
- 1. the quantity of matter which a body contains, as measured by its acceleration under a given force or by the force exerted on it by a gravitational field.
- 7. a state in which opposing forces or influences are balanced.
- 10. is the force that attracts two bodies toward each other,
- 11. a force acting briefly on a body and producing a finite change of momentum.
- 12. the resistance that one surface or object encounters when moving over another.
- 14. a property of matter by which it continues in its existing state of rest or uniform motion in a straight line, unless that state is changed by an external force.
Down
- 2. the rate of change of velocity per unit of time.
- 3. the speed of something in a given direction.
- 4. when one object strikes another
- 5. a quantity that has magnitude and direction and that is commonly represented
- 6. (of a quantity) having only magnitude, not direction.
- 8. the quantity of motion of a moving body, measured as a product of its mass and velocity.
- 9. the force exerted on the mass of a body by a gravitational field.
- 12. an influence tending to change the motion of a body or produce motion or stress in a stationary body. The magnitude of such an influence is often calculated by multiplying the mass of the body by its acceleration.
- 13. the indefinite continued progress of existence and events in the past, present, and future regarded as a whole.
