Newton’s Laws of Motion
I. Newton’s First Law of Motion
Every body continues in its state of rest or of constant speed in a straight line unless it
is compelled to change that state because of forces acting on it.
According to Newton’s first law, an object sitting at rest will remain at rest if the sum of
all forces acting on the object is zero. Similarly, if an object is moving and if the sum of
the forces acting on the body is zero, then the object will continue to move in the same

direction with the same speed. This tendency of object to remain at rest or to continue
in motion is called inertia. To change the motion of an object with inertia, unbalanced
forces must act on the object.
II. Newton’s Second Law of Motion
An unbalanced force acting on an object will cause the object to accelerate in the
direction of the force. The acceleration is directly proportional to the resultant force acting
on the object and inversely proportional to the object’s mass. If a group of forces act on
an object of mas m, the vector sum of these forces causes the object to have an
acceleration a, given by
𝑎 =
∑ 𝐹
𝑚
∑ 𝐹 = 𝑚𝑎
The direction of a is in the direction of the resultant force.
Newton’s Second Law is often written as 𝐹 = 𝑚𝑎. The force F on the left side of the
equation, however represents the net or resultant force acting on the object. For
example, if three forces F1, F2 and F3 act on an object, then
∑ 𝐹 = 𝐹1 + 𝐹2 + 𝐹3 = 𝑚𝑎
Note that if the forces acting on an object add to zero, the object’s acceleration is zero.
If the object is at rest, it remains at rest, if it is moving, its velocity remains constant.
III. Newton’s Third Law of Motion
Whenever one object exerts a force on a second object, the second objects exerts a
reaction force of equal magnitude but opposite direction on the first object.
Definition of Terms:
Normal Force (N) – a force which ids perpendicular to the surface
Weight (W) – a force which is perpendicular to the ground/ horizontal
μ – coefficient of friction
Frictional force – a force which opposes the direction of acceleration (𝑓 = 𝜇𝑁)
Additional Formula:
𝐹 = 𝑚𝑎
∑ 𝐹
𝑥 = 𝑚𝑎𝑥
∑ 𝐹
𝑦 = 𝑚𝑎𝑦
