What is a reference point?
Newton's First Law of motion is often referred to as this.
What is the Law of Inertia
Resistance to change
What is Inertia?
A see saw is an example of this simple machine
1 class lever
This force can only attract two objects that have mass
What is gravitational force?
Distance / Time=
What is speed
An object will stay in motion with a constant velocity (or will stay at rest) until it is acted on by an outside force.
What is Newton's First Law of Motion
Force resulting from surfaces rubbing against one another
What is friction?
The center of a first class lever
What is a fulcrum?
The strongest natural force that keeps protons from repelling each other in the nucleus of an atom
What is strong force?
The speed of an object in a given direction
What is velocity?
F= m x a
What Newton's Second Law of Motion?
A push or a pull exerted on an object in an effort to change that object’s velocity.
What is force?
A ramp is an example of this simple machine.
What is an inclined plane?
What is electromagnetic force?
The study of motion in physics
What is mechanics?
Newton's Third Law states this
For every action, there is an equal and opposite reaction.
A car is speeding up, which is an example of this
What is positive acceleration?
Bikes use this simple machine
What is a wheel and axle?
The area around an object where magnetic forces act
What is a magnetic field?
Acceleration in the opposite direction as the object’s velocity.
What is negative acceleration?
Explosive force from combustion pushing down to propel an object in opposite direction.
What is thrust?
A driver is using cruise control and is moving at 55mph North with this kind of acceleration
What is zero acceleration?
This simple machine changes the direction of the force. Hint: slice and dice
Tiny regions where magnetic fields of atoms are grouped together and aligned
What are magnetic domains?
