Newton's First Law
An object at rest remains at rest unless an
unbalanced force acts on it.
Newton's Second Law
The acceleration of an object as produced by a net
force is directly proportional to the magnitude of the
net force, in the same direction as the net force, and
inversely proportional to the mass of the object.
Force= mass x acceleration
Newton's Third Law
Every action force has an equal reaction force.
Force is push or a pull.
Force makes an object start moving, slows down,
and change direction.
Forces are vectors.
The sum of all forces acting on an object.
It is the inertia of motion.
The more the momentum is, the harder to stop the
Equation: P=m x v
Momentum= Mass x Velocity
Mass is amount of matter in an object.
The object's inertia depends on mass.
The more acceleration, the more he change in force
acts on the object.
Acceleration is the change in velocity.
In this equilibrium, the object change the motion.
The object stays at rest all the time.
It is when all the forces cancel out each other and
the object stays the same.
The sum is zero.
Free Body Diagram
It is the diagram used to describe the forces acting
on an object and in which direction they are acting
on it. It shows the relation between the magnitude
and the direction of the forces.
Objects bounce off one another.
Objects collide and stick to each other.
Friction is the force that opposes motion.
Friction is more on the rough surfaces which slows
down the object's speed.
Friction is less on the smooth surfaces which moves
the object very smoothly.
