Newton’s Laws
This is a push or pull
What is a Force
what is the definition for ¨Momentum¨
the project of an object´s mass and velocity
what are the units for work
Joules (J)
1J = 1N x m
what is called when objects move with constant velocity
what is uniform motion
Electricity is the movement of:
what is electrons
if a body is at rest or moving at a constant speed in a straight line,
what is Newton´s First Law
units for momentum
what is kg x m / s
These are the two variables that kinetic energy is dependent upon
What are mass and velocity?
The speed at which an object is traveling and the direction it is traveling.
What is velocity?
11 protons and 16 electrons
-5
when there is no ¨net force¨ acting on an object it will - remain at rest and move with constant velocity in a straight line
what is ¨Equilibrium¨
The impulse an object undergoes is equivalent to its?
What is a change in momentum
the energy an object possesses due to its motion
Kinetic Energy(KE)
the rate at which the velocity of an objects changes
what is acceleration
Force objects exert on each other due to their charge
what is Static Electricity?
An object resistance to change in motion
what is the Law of Inertia
Name one type of Collision
what is Elastic or Inelastic
This is the relationship between Net Work and Kinetic Energy
What is Net Work = change in KE
what is acceleration due to earth's gravity
g = 9.81 m/s2
This is an object that has more electrons than protons.
What is a negatively charged object?
An example of law - the baseball force the bat to the left, the bat forces the ball to the right
what is Newton´s 3rd Law
A bullet traveling at 900m/s has a momentum of 4.5kg*m/s. The mass of this object is this.
What is .005kg
If I do 2000 Joules of work in 5 seconds, I produce this amount of power.
What is 400 watts.
an object falls freely from rest. what is its velocity after 4 s
vf = vi + a t
vf = 0 +(9.81)(4)
vf = 39.24m/s
what is called when electrons allow a path to or from the ground.
what is grouding
