The Material World

2. A scalar quantity that has magnitude showing the path travelled from one point to another
4. A force of attraction between particles or bodies that occurs because of their mass
9. A vector quantity that has a direction and magnitude showing the direct movement from the origin to the endpoint
12. Something which does not change
13. The push and pull of an object with mass that cause it to change its velocity
15. The condition of a system when neither its state of motion nor its internal energy state tends to change with time
16. Relating to or resulting from the motion of material bodies and their energies and forces
17. Used to indicate things that are in a state where they are able to change

1. A curve representing such a rate of change.
3. The measure of the force of gravity acting on a body
5. The directional speed of an object in motion
6. measures how much a system is getting out of the fuel or primary energy flow it is using
7. The vector sum of two or more vectors
8. The idea that an object will continue its current motion until some force causes its speed to stop
10. Speed The rate at which velocity changes with time, in terms of both speed and direction
11. A dimensionless quantity representing the amount of matter in a particle or object
14. A force that causes things to move, divided into two types: kinetic and potential
