force is a push or a pull
First law of motion is a body remains at constant velocity unless an unbalanced force acts on it
What is inertia to continue in a straight line unless acted upon a force.
Gravity is a force
friction incolved in a wagon moving down a hill is rolling friction
As the force acting on you increases, your acceleration increases
The unit of force is the newton
if you go to the moon your mass remains the same
as you glide across a frozen pond it is called sliding friction
an ant falling from the roof of a house lands unharmed because of air resistance
Secound law of motion is an object acted on by an unbalanced force will accelerate in the direction of the force with an acceleration given by the following acceleration.
Third law of motion is forces always act equal to each other.
friction is the force that resists sliding motion between surfaces that are touching
relative motion an object's position change is described in terms of a reference point
constant speed is the same at any given moment in time
contact force involves objects touching each other
long-rang forces include gravityu, magnetism, and electricity
Inertia measures an object's tendency to remain at rest or keep moving
balanced forces forces that are equal but in opposite directions canceling each other
Unbalanced forces if one force is greater that another, a change in motion
static friction keeps a stationary object from moving on a surface when a force is applied to the object
Amachine that uses only one movement simple machine
the force you apply when using a machine input force
probably the first simple machine lever
mechanical advantage is the number of times the applied force is increased by a machine.
