1. Simple machines-A machine with few or no moving parts. Simple machines make work easier.

2. Compound machines-Two or more simple machines working together to make work easier

3. Force- any influence that causes an object to undergo a change in speed, a change in direction, or a change in shape

4. Friction- is the force resisting the relative motion of solid surfaces, fluid layers, and/ or material elements sliding against each other

5. Gravitation- is a natural phenomenon by which physical bodies attract with a force proportional to their mass

6. Magnetism-  is a property of materials that respond at an atomic or subatomic level to an applied magnetic field.

7. Work- is a scalar quantity that can be described as the product of a force times the distance through which it acts

8. Newtons- is the SI derived unit of force

9. Joules- is a derived unit of energy or work in the International System of Units.

10. watts- unit of power 

11. acceleration-is the rate of change of velocity with time

12. balanced forces- two equal forces are applied on an object pushing both ways

13. unbalanced forces- produce a non-zero net force, which changes an object's motion.

14. inertia- resistance of any physical object to a change in its state of motion or rest, or the tendency of an object to resist any change in its motion

15. power- rate at which energy is transferred, used, or transformed

16. speed- the magnitude of its velocity or the rate of change of its position

17. velocity-speed in a given direction

18. kinetic energy-object is the energy which it possesses due to its motion

19. potential energy-the energy of a body or a system with respect to the position of the body or the arrangement of the particles of the system

20. machines-manages power to accomplish a task

21. momentum- given object and find out how much energy it carries
