Dynamics
This property only depends on the two materials that are in contact with each other.
What is the coefficient of friction?
As you put a heavier mass on a spring and let it oscillate, this happens to the period.
What is the period increases?
What is 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.
Who is (Thomas) Young?
This force is always perpendicular to the surface
What is the normal force?
As a skier goes down a mountain, the amount of gravitational potential energy does this.
What is decreases?
The electric field at a distance of 1.0 m from a charged sphere is 100 N/C. At this EXACT distance from the sphere, the electric field be 50 N/C.
What is root 2 meters (1.4 m)?
In order for nodal lines to be seen, this has to happen.
What is waves have to interfere destructively.
You never draw this force on a free-body diagram (FBD).
What is net force?
The value that tells us the relative stiffness of a spring.
What is 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.
What is 40 J?
This type of opening creates an interference pattern with a centre maximum that is brighter and wider than the other maxima.
What is a single slit?
What is another name for Newton's First Law?
What is Law of inertia?
As a spring is stretched out to the right, this is the direction of the spring force.
What is 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.
What is 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.
What is 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.
What is 2F?
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.
What is out of the page?
This happens to the interference pattern in a double slit experiment as the distance between the slits increases.
The maxima become narrower.
