What is Newton's third law?
Energy is transferred from kinetic to this stored energy form
Unit for work and energy
What is Joule?
State the 3 laws of motion
Who is Isaac Newton?
Which law- It requires more force to pull a wagon with someone in it than an empty wagon.
Unit for force
What is Newton (N)?
Energy of motion
What is kinetic energy?
Mass * acceleration will calculate an objects
What is force?
What is the name of a force labeled "Fn"?
What is normal force?
I am riding a bike. I hit a fence, stopping the bike, but sending me over the handlebars. Which of Newton's Laws explains why this happens?
1st Law: Law of Inertia
An object in motion stays in motion, an object at rest stays at rest, unless acted on by an outside force
The equation for force
What is F=MA
Potential energy is greatest at this point on a roller coaster?
What is the top of a hill?
Acceleration due to gravity (#)
What is 9.8m/s2
This is an opposing force acting against objects.
What is friction?
Newton's second law is also referred to as this
What is law of acceleration?
When drawing force diagrams this represents which way an object will move.
What is a longer arrow?
As potential energy decreases this happens to total energy.
What is nothing?
Unit for velocity
What is meters/second
This must act on an object in order for the direction or speed of an object to change.
What is unbalanced force?
Word definition: Object at rest will stay at rest unless outside force acts upon it.
What is inertia?
Force that acts on all objects everywhere
What is gravity?
Energy that is not transferred from kinetic to potential becomes this.
If the net force on an object is zero, then the object is in...
What is equilibrium?
energy that is possessed by an object due to its motion (kinetic) or due to its position (potential).
What is mechanical energy?
