force and motion

5. The force that attracts objects towards each other due to their masses
6. The force that keeps an object moving along a circular path
8. The opposing force experienced by objects moving through air
10. Scientists systematically investigate nature by observing, forming hypotheses, experimenting, analyzing data and drawing conclusions.
12. A measure of the heaviness of an object, determined by its mass and gravity acting on it
13. A controlled procedure carried out under specific conditions to test a hypothesis or validate scientific theories
14. The distance and direction from the starting point to the ending point
15. The force that prevents two stationary surfaces from sliding past each other
17. A force that acts towards the center of a circular path, keeping an object moving in a curved trajectory.
18. The speed and direction of an object's motion
19. For every action, there is an equal and opposite reaction.

1. When all forces acting on an object cancel each other out
2. The rate at which an object changes its velocity
3. The tendency of an object to resist changes in motion
4. The product of mass and velocity, used to measure how hard it is to stop a moving object
7. The force that opposes the motion between two surfaces in contact with each other
9. The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.
10. A proven scientific explanation based on evidence accepted by experts.
11. The rate at which an object moves or the distance covered per unit of time.
16. A push or pull that can change the motion of an object
