Laws of Motion
The 4 types of friction are _____, ____, _____, and _______.
Sliding
Fluid
Static
Rolling
A Push or pull that acts on an object.
Force
The SI unit of force.
Newton
The overall force acting on an objects after all forces combined
Net Force
Force that opposes the motion of an object that touch as they move past each other.
Friction
Friction force that acts on objects that aren't moving.
Static Friction
Friction force that acts on objects that aren't moving.
Static Friction
Force that opposes the direction of motion of an object as it slides over a surface.
Sliding Friction
Friction force that acts on rolling objects.
Rolling Friction
Opposes motion of an object through a fluid.
Fluid Resistance
Air Resistance
Fluid friction acting on an object moving through the air.
Force that acts between any two masses.
Gravity
Constant velocity of a falling object when the force of air resistance equals the force of gravity.
Terminal Velocity
Falling object (projectile) after it is given an initial forward friction.
Projectile Motion
Who is the Italian scientist who did experiments that helped correct misconceptions about force and motion?
Galileo
Who was the Ancient Greek philosopher who made many scientific discoveries through observations and logical reasoning?
Aristotle
According to Newton's first law of motion, the state of motion of an object
does not change as long as the net force acting on the object is zero
How does a zero net force affect an object's motion?
The state of motion of an object does not change
Who is the scientist who studied in England and introduced several laws describing force and motion.
Newton
