forces vocab

2. body diagram-graphical sketch in physics that isolates an object and shows all external forces acting on it
4. force required to accelerate a 1-kilogram mass by 1 meter per second squared
9. force-total force acting on an object
10. resistance to any change in its state of motion
13. the rate of change of velocity with respect to time
15. or a pull on an object that can cause it to change its motion, direction, or shape
16. where the net force and net torque on an object are both zero

1. that has both magnitude (size or length) and direction
3. of gravity acting on an object's mass
5. single force or vector that represents the combined effect of two or more other forces or vectors
6. that opposes the relative motion or intended motion between surfaces in contact
7. field-mathematical description of the distribution of a non-contact force in space
8. at which an object covers distance
11. measure of the amount of matter in an object, which also determines its inertia, or resistance to acceleration
12. force-contact force exerted by a surface that is perpendicular to the surface itself
14. of mass-the unique point where the weighted relative position of the mass of a system sums to zero
