Motion
When an object changes in position in comparison to a reference point
What is motion?
An action exerted on an object in order to change its state of rest or motion
What is force?
important scientist that developed the laws of motion
Who is Sir Isaac Newton?
a quantity defined as the product of the mass and velocity of an object
What is momentum?
the distance an object travels divided by the time of travel
What is speed?
It is the sum of forces applied on an object
What is net force?
An object at rest remains at rest unless it experiences an unbalanced force
what is the First law of newton?
When an objects exerts an action force on a second object, the second object exerts a reaction force on the first object. (Sylvia, don't hit the table)
What is the third law of newton?
The unit to measure speed
What is meters per second?
Objects that do not move because they have a net for of zero
What is balanced force?
It is the property of matter that resists change in motion
What is inertia?
non contact force that attract objects toward each other.
Speed with direction
What is velocity?
it causes objects to move, having a net force bigger than zero
What is unbalanced force?
The force action on an object equal to the object's mass times its acceleration
What is the second law of newton?
the force exerted by magnets when they attract or repel each other.
What is magnetism?
The line on a distance-time graph that represents the speed of an object
What is the slope?
A force that opposes motion between the surfaces that are in contact
What is Friction?
Change of velocity over time
What is acceleration?
The ends of a magnet (they always have two)
