What is classical physics?
100
This refers to the number of waves which pass a point per unit of time
What is frequency?
100
This law states that the velocity of an object does not change unless the object is acted upon by an outside force
What is Newton's first law of motion?
100
This term refers to a change in the course of a wave as a result of a collision with an object or boundary
What is reflection?
100
This machine is a combination of at least one fixed pulley and at least one movable pulley

200
This type of quantity has both magnitude and direction
What is a vector?
200
The type of wave in which the particles of the medium oscillate at right angles to the direction of wave motion
What are transverse waves?
200
This law states that the angle of incidence equals the angle of reflection
What is the law of reflection?
200
The spreading out of a wave after it passes through a narrow opening

300
Any change in velocity whether a change in speed or a change in direction
What is acceleration?
300
This term refers to the maximum distance that particles are displaced by a wave
What is amplitude?
300
This law states that for every action there is an equal and opposite reaction
What is Newton's third law of motion?
300
This refers to the reinforcement or cancellation that occurs when two or more waves meet

400
The SI unit of force
What is the newton?
400
This term refers to the distance between any two corresponding points on adjacent waves
What is wavelength?
400
This law states that when the overall external force acting on a system is zero, the momentum of the whole system remains constant
What is the law of conservation of momentum?
400
The bending of the path of a wave as a result of a change in the wave's speed
What is refraction?
400
This device uses reflected radio or microwaves to measure the distance and direction to objects
