Momentum and Collisions
1-Dimensional Kinematics
100
An object in motion stays in motion OR an object at rest stays at rest UNLESS acted upon by an outside force
What is Newton's first law
100
The ability to do work
What is Energy
100
can be described as the effect produced by a moving source of waves in which there is an apparent upward shift in frequency for observers towards whom the source is approaching and an apparent downward shift in frequency for observers from whom the source is receding.
What is Doppler Effect
100
An object that is moving at constant speed
What is momentum
100
The mathematical quantites that are used to describe the motion of an object can be divided into what to categories
What is Vector and Scalar
200
For every action, there is an equal and opposite reaction
What is Newton's third law
200
Something that is done on an object that applies force to move it through a distance
What is Work
200
(Speed= Wavelength*Frequency) A copper medium has a wavelength of 1.19 meters and a frequency of 2.1Hz. Calculate its speed
What is 2.5m/s
200
The momentum of an object varies with the speed of the object TRUE or FALSE
TRUE
200
Quantities that are fully described by both a magnitude and direction
What is Vector
300
A car abruptly comes to a stop but you continue forward until your seatbelt restrains you.
What is Newton's first law
300
The energy of an object in motion
What is Kinectic energy
300
Waves in which the motion of the individual particles of the medium is in a direction that is parallel to the direction of energy transport.
What is Longitudinal Wave
300
An event where momentum or kinetic energy is transferred from one object to another
What is Collision
300
Quantites that are fully described by a magnitude alone
What is Scalar
400
The acceleration of an object is dependent on the net force and the mass of an object
What is Newton's second law
400
The ability of a system to do work due to its position or internal structure
What is Potential energy
400
An electromagnetic wave that travels through the vacuum of outer space
What is Light
400
Two rubber balls collide into each other and "bounce" apart after they hit.
What is Inelastic collision
400
A vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position
What is Displacement
500
Acceleration= mass/force
What is Newton's second law
500
The work is calculated as force*displacement*cosine(theta) where theta is the angle between the force and the displacement vectors. EX: a 100N force is applied to move a 15 kj object horizontal distance of 5m at constant speed. What is the work done?
W = (100 N) * (5 m)* cos(0 degrees) = 500 J
500
It is possible to transform unpolarized light to polarized light TRUE or FALSE
TRUE
500
Momentum= mass*velocity. Determine the momentum of a 1000-kg car moving northward at 20 m/s
20 000 kg•m/s, north
500
A physics teacher walks 4 meters East, 2 meters South, 4 meters West, and finally 2 meters North.
