Motion
This is the formula for velocity
What is distance/time
This force acts perpendicular to a surface and supports the object on the surface.
What is normal force
This is energy in motion.
What is kinetic
This is the top part of a wave
What is crest
The flow of electrons through a wire.
What is current?
A change in velocity is called this
What is acceleration
What is the net force of box being pushed 45 N to the left with a frictional force of 30 N to the right.
What is 15 N left
Energy is measured in this unit
What is Joules
This determines the loudness of a sound wave.
What is amplitude
Electric Potential is the same as this
What is voltage
What hits the ground first when dropped from a cliff: a bowling ball or a golf ball
What is they hit at the same time due to acceleration of gravity
The acceleration of an object that has a net force of 6 N left and a mass of 0.5 kg.
What is 12 m/s^2?
A height increases, what happens to potential energy?
What is it also increases
The speed of ultraviolet waves.
What is 3 x 10^8 m/s?
This is the only part of the atom that is able to move and transfer.
What is electrons
Solve for the following: a 1 kg beach ball going 4 m/s collides with a second 0.5 kg beach ball at rest. What is the velocity of the 0.5 kg beach ball after the collision if the 1 kg beach ball stops.
What is 8 m/s
What must happens to force to create the same acceleration if mass increases by a factor of 4?
What is the force is quadrupled.
The total amount of energy in a system must remain constant.
What is conservation of energy?
What is decreases?
What is 4N?
The total amount of momentum before a collision must equal the total amount of momentum after a collision.
What is conservation of momentum?
This is what happens if the force is held constant, but the mass of the object doubles.
What is acceleration is cut in half.
An 2 kg object starts with 20 J of potential energy at the top of a hill. As the object starts to go down the hill the PE is turned into KE. What is the velocity of the object at the bottom of the hill?
What is 4.5 m/s?
The reason that sound travels faster in water than in air.
What is a more dense medium?
How to you increase the magnetic field on an electromagnet?
What is increase the # of coils around the nail
