1D & 2D Motion
A quantity that has both magnitude and direction
What is a Vector?
An object will remain in its state of motion until an unbalanced force acts on it.
What is Newton's First Law of Motion?
The energy an object or body possess due to its position relative to other or to the Earth.
What is Potential Energy?
A traumatic brain injury.
What is a concussion?
What is the highest point of a wave oscillation or cycle?
What is a Crest?
9.81 m/s2
What is gravity? or What is g?(Numerical value)
The net force of an object is equal to the objects mass multiplied by its acceleration.
What is Newton's Second Law?
Joules
What is the unit for Energy?
A collision is in which there is a no net loss of kinetic energy in a system and results in a perfect rebound.
What is an Elastic Collision?
c = 3.0 x 108 m/s
What is the Speed of Light?
The change in velocity of an object over time.
What is acceleration?
For every action, there is an equal and opposite reaction.
What is Newton's Third Law?
A mechanical device that changes the magnitude or direction of a force in order to make completing a task easier.
What is a Simple Machine?
A collision that results in kinetic energy being lost in a system. This can lead to crumple zones between the objects colliding.
What is an Inelastic Collision?
A form of electromagnetic radiation that is used for cellular communication, used for stimulating polar molecules in food, and range from one meter to one millimeter.
What are microwaves?
The variable that denotes vertical displacement, or height.
What is ∆y?
The pulling force transmitted when a cable, rope, wire, or string is tethered by forces acting on opposite ends.
What is Tension Force?
Energy cannot be created or destroyed, only transferred.
What is the Law of Conservation of Energy?
In a frictionless system, the total momentum (p2 and p1) remains constant throughout the collision if no external forces are acting on it.
What is (the law of) Conservation of Momentum?
The process of waves changing their velocity and changing their direction when traveling from one medium to another.
What is Refraction (of light)?
The movement of an object or body only under the influence of gravity
What is Free Fall?
The contact force that surfaces exert to prevent solid objects from passing through each other. It is made possible through the electrons that are in objects.
What is the Normal Force?
The sum of kinetic, gravitational potential, and elastic potential energy in a system.
What is Mechanical Energy?
The effect of force acting over time on an object in order to change its Momentum.
What is Impulse?
The change in frequency of a wave in relation to an observer who is moving relative to the wave source.
What is the Doppler Effect?
