STEP 3: Give guided practice using appropriate Graphic Organisers
Frictional Force
Magnetic Force
HOW SIMILAR?
Both produce heat
Both are forces
Depend upon mass
Unit for both forces are Newton (N)
HOW DIFERRENT?
With regards to?
There are negative and positive
effect
Effect
Attraction or repulsion that
arises between electrically
charged particles because of
their motion
Friction is contact force
Types of force
No contact force
Friction always resistive of
motion
Motion
Can make emf and can rotate
a coil
Opposite to the velocity vector
Direction
Perpendicular to the plane
formed by magnetic field
𝑓 = 𝜇𝑁
Formula
𝐹 = 𝑞𝑣𝐵 sin ∅
PATTERNS OF SIGNIFICANT SIMILARITIES AND DIFFERENCES
Both are forces. Magnetic force is two charge meet in magnetic field which can produced
by current flow in conductor. Meanwhile friction force is force created by two surface in
contact in static and dynamic friction.
CONCLUSION OR INTERPRETATIONS
Magnetic field influenced on frictional force. Magnetic force exist when the presence of
current flow in conductor which produced magnetic field that react between charge in it.
Frictional force is the force produced when two objects in contact with each other in a
surface.
