Physics

2. unit of mass
4. measure of how close a measurement is to the true value of the quantity being measured.
8. velocity is not changing in magnitude and in direction both.
11. force acting on unit area of a surface.
15. the difference of electrical potential between two points.
17. fundamental interaction which causes mutual attraction between all things with mass or energy
18. a variable (often denoted by x ) whose variation does not depend on that of another.
19. interaction that occurs between particles with electric charge via electromagnetic fields.
21. unit used to calculate the force
23. empirical law which states that the force needed to extend or compress a spring by some distance scales
24. the scientist who discovered gravity
26. Getting faster
27. the change in position of an object
28. physical attributes that occur through a magnetic field, which allows objects to attract or repel each other.

1. the basic photometric value, expressing the capacity of a point light source to provide illumination in a given direction.
3. the to and fro motion of an object from its mean position
5. force transmitted through a rope, string or wire when pulled by forces acting from opposite sides.
6. significant figures in a measurement include all of the digits that are known, plus one last digit that is estimated.
7. modern form of the metric system and the world's most widely used system of measurement
9. measure of how close a series of measurements are to one another. A measure of how exact a measurement is.
10. the scientist who discovered inertia
12. unit of length
13. force that is caused by air.
14. how to calculate speed
16. Electrostatic, Gravitational, Magnetic which does not require surface contact and may pass through space.
20. pressure is the pressure of air around us.
22. measure of energy transfer that occurs when an object is moved over a distance by an external force at least part of which is applied in the direction of the displacement.
25. object’s speed in a given direction
