Across
- 2. strength or energy as an attribute of physical action or movement.
- 3. the speed of something in a given direction
- 6. energy
- 7. the SI unit of power, equivalent to one joule per second, corresponding to the power in an electric circuit in which the potential difference is one volt and the current one ampere.
- 12. Gravitational potential energy is energy an object possesses because of its position in a gravitational field.
- 13. An inelastic collision, in contrast to an elastic collision, is a collision in which kinetic energy is not conserved due to the action of internal friction.
- 14. activity involving mental or physical effort done in order to achieve a purpose or result.
Down
- 1. 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.
- 4. Elastic potential energy is Potential energy stored as a result of deformation of an elastic object
- 5. A perfectly elastic collision is defined as one in which there is no loss of kinetic energy in the collision.
- 8. Mechanical energy is defined as the energy of an object or system due to its motion or position.
- 9. the SI unit of work or energy, equal to the work done by a force of one newton when its point of application moves one meter in the direction of action of the force, equivalent to one 3600th of a watt-hour.
- 10. the strength and vitality required for sustained physical or mental activity
- 11. the energy possessed by a body by virtue of its position relative to others, stresses within itself, electric charge, and other factors.
