Dynamics
This property only depends on the two materials that are in contact with each other.
The coefficient of friction
As you put a heavier mass on a spring and let it oscillate, this happens to the period.
The period increases
The speed of an object in orbit does not depend on this.
The mass of the object
This physicist's experiment proved that Huygen's wave model of light described light's behaviour more accurately than Newton's particle model of light.
(Thomas) Young
This force is always perpendicular to the surface
The normal force
As a skier goes down a mountain, the amount of gravitational potential energy does this.
Decreases
The electric field at a distance of 1.0 m from a charged sphere is 100 N/C. At what distance is the electric field 50 N/C?
Square root 2 m (1.4 m)
In order for nodal lines to be seen, this has to happen.
Waves have to interfere destructively.
You never draw this force on a free-body diagram (FBD).
Fnet
For circular motion Fc
The value that tells us the relative stiffness of a spring.
The spring constant
This is the amount of kinetic energy obtained by a 5 C charge as it moves through a potential difference of 8 V.
40 J
This type of opening creates an interference pattern with a centre maximum that is brighter and wider than the other maxima.
A single slit
What is the name for net force in circular motion?
Centripetal Force
As a spring is stretched out to the right, this is the direction of the spring force.
To the left
When a conductor is carrying a current, there will be no force acting on it when the conductor is placed at this angle relative to an external magnetic field.
When they are parallel (0 or 180 degrees)
This type of opening that light goes through produces an interference pattern on a screen that has very defined bright spots, with large dark gaps in between.
A diffraction grating
A person is going upwards in an elevator. How does does their apparent weight compare to the force of gravity as the elevator accelerates upwards?
Apparent weight (normal force) is larger than force of gravity.
An object is in uniform circular motion with speed "v" and centripetal force "F". This is the new value of "F" when the radius of the path is halved and the velocity is kept the same.
2F (Double the original force)
A current flows in a conductor from east to west inside a magnetic field that is pointing south. The magnetic force is in this direction.

This happens to the interference pattern in a double slit experiment as the distance between the slits increases.
The maxima become narrower.
