SCIENCE ( 1.1 )

Question 1

The push or pull on an object with mass causes it to change its velocity.

Answer 1

force

Question 2

refers to the size or strength of the force. It is commonly expressed in
newton (N) for Meter-Kilogram-Second (MKS) system, dyne (dyn) for
Centimeter–Gram–Second (CGS) system and pounds (lbs) for Foot– Pound–Second
(FPS) system. In the International System of Units (SI), newton is commonly used
which is named after Sir Isaac Newton, an English physicist and mathematician.

Answer 2

magnitude

Question 3

points to where the object goes. The direction of the arrowhead indicates
the direction of the force. The length of the arrow represents the amount of force
(relative magnitude).

Answer 3

direction

Question 4

the location of where the force is applied.

Answer 4

point of application

Question 5

is the straight line passing through the point of application and is
parallel to the direction of force.

Answer 5

line of action

Question 6

There are two types of force, namely ________ and _________.

Answer 6

contact forces and non-contact forces.

Question 6

forces where objects touch or contact with each other.

Answer 6

Contact forces

Question 7

a force given to a person or object by another person or object. Its
symbol is F depending on who or what applies force to the object. In the image
below, we could denote the applied force with F A or F M to denote applied force of the
man.

Answer 7

Applied force

Question 7

is the force acting against or opposite an object in contact with which
makes the movement of the object slow down.

Answer 7

Friction

Question 8

is the force that acts perpendicular to the surface of the object in
contact with. Its symbol is F N or simply a capital N.

Answer 8

Normal force

Question 8

is the force applied to string, rope, chain or cable. Its symbol is F T or
simply T.

Answer 8

Tension

Question 9

forces where objects do not touch or contact with each other.
These forces act over a zone or area called field.

Answer 9

Non-contact forces

Question 10

is the force of attraction between two objects. In the
case of the Earth, this gravitational force causes objects to fall down to the ground.

Answer 10

Gravitational force

Question 10

are forces exerted on a field of attraction or repulsion as in the
case of magnets and other magnetic materials.

Answer 10

Magnetic forces

Question 10

is the attractive or repulsive interaction between any two charged
bodies.

Answer 10

Electric force
