Physics

1. have magnitude and direction.
3. rate object covers distance.
6. to resist changes in its state of motion.
8. velocity changes over time.
9. graphical representation of all forces action on a object for its motion/equilibrium,
10. unique point where all mass can be considered concentrated.
12. opposes the motion between 2 surfaces in contact.
14. Region of space where an object has non contact force.
15. causes change in motion shape or size.
16. amount of matter in sum/ resistance to acceleration.

2. single vector that represents the combined effect of 2 or more vectors like forces and velocities.
4. overall force acting on an object by vector sum of all individual forces both magnitude and direction.
5. forces of gravity on an object.
7. perpendicular contact force exerted by a surface on a object resting on it.
11. state where an object is balanced.
13. force required to accelerate a 1 kg mass rate of 1 m/s.
