<span>Force is needed to change an objects state of motion and it is always a part of a mutual action that involves another force. The force can be push or pull.</span>
A ball that moves when kicked <span>describes a force acting on an object.
</span><span>The force is a vector quantity, because it that needs both magnitude and direction in order to be defined.</span>
Plane mirrors and convex mirrors only produce virtual images. Only a concave mirror is capable of producing a real image and this only occurs if the object is located a distance greater than a focal length from the mirror's surface. And the upright images produced by plane mirrors have the same size as the object.
Answer:
the answer the correct one is the d
Explanation:
In the gate rotation experiment several things are measured.
- the distance from the hinges to the applied force, which must be measured with a tape measure
- The value of the force that is devised with a dynamometer
- the rotated angle that is measured with a protractor
- the time it takes to turn an angle, which is measured with a stopwatch
When examining the answer the correct one is the d
Friction resists motion.
Friction is a contact force.
<span>Friction is caused by microscopic bumps and ridges on surfaces.

They all correct, just took the quiz.
Answer:
If W = 50 N object weighs 50 N
We = (50 - 30) N net force on falling object since the weight and the air resistance are in different directions
We =20 N effective weight of falling object (causing it to fall more slowly)
