The forces and movement
- Forces and balance
- A force is a push or pull upon
an object resulting from the
object's interaction with
another object. Whenever
there is an interaction
between two objects, there is
a force upon each of the
objects. Forces only exist as a
result of an interaction.
- Newton
- Its units are Newtons (N)
- Its units are Newtons (N)
- Force as a vector
- Force module
- Numerical value of the strength of the force
- Numerical value of the strength of the force
- Force direction
- Line that contains the value of the force
- Line that contains the value of the force
- Force sense
- Indicated by the arrow of the vector
- Indicated by the arrow of the vector
- Force module
- Composition of forces and balance
- Resultant force
- This is a single
force that has the
same effect on the
object as all the
individual forces
acting together.

- Effects of forces
- Alterations of the state of movement
- Newton's first law.
Law of inertia
- An object at rest stays at rest and an
object in motion stays in motion with
the same speed and in the same
direction unless acted upon by an
unbalanced force.
- An object at rest stays at rest and an
object in motion stays in motion with
the same speed and in the same
direction unless acted upon by an
unbalanced force.
- 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.
- F = m*a
- F = m*a
- Newton's third law.
- For every action, there is
an equal and opposite
reaction.
- For every action, there is
an equal and opposite
reaction.
- 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.
- Newton's first law.
Law of inertia
- Alterations of the state of movement
- If the net force is zero, the acceleration is zero, and the velocity does not
change, it is constant; therefore, the movement can be: Uniform rectilinear
movement (MRU) or it can be an object at rest.
- F=0
- F=0
- If the net force is not zero, the mobile has acceleration (or deceleration); therefore, the
movement is uniformly varied or Uniformly accelerated or uniformly retarded.
- F ! = 0
- F ! = 0
