Lesson 1: Force and Motion

Question 1

It is the EQUAL FORCES acting on one object in opposite directions and does NOT change the object in motion

Answer 1

Balanced Force

Question 2

When there is an UNBALANCE on the forces acting on one Object

Answer 2

Unbalanced Force

Question 3

It is the SUM of all forces acting on an Object

Answer 3

Net force / Resultant Force

Question 4

What are the 2 MAIN types of Forces?

Answer 4

• Contact Forces
• Non Contact Forces

Question 5

Are the Forces wherein Objects TOUCH/CONTACT with each other

Answer 5

Contact Forces

Question 6

Are the Forces where Objects DO NOT TOUCH/MAKE CONTACT with each other

Answer 6

Non Contact Forces

Question 7

Non Contact Forces Act over a ZONE / AREA called a_____?

Answer 7

Field

Question 8

What are the 4 forces that are UNDER Contact Force?

Answer 8

• Normal Force
• Friction Force
• Applied Force
  -Frictional Force

Question 9

It is A force that ACTS AGAINST/OPPOSITE an Object In Contact with which makes the Movement of the Object Slow Down

Answer 9

Friction Force/Friction

Question 10

It is the force that is APPLIED to an Object by a person or another object

Answer 10

Applied Force

Question 11

Force that opposes the relative motion / TENDENCY OF SUCH MOTION OF 2 SURFACES in Contact

Answer 11

Frictional Force

{NoteMagkaiba toh sa Friction/Friction Force since this is about the motion of 2 SURFACES :]]
and not the movement of the object}

Question 12

A CONTACT FORCE that is perperndicular to the surface that it contacts

Answer 12

Normal Force

Question 13

This is known as “The push and pull” and what causes an Object to move, move faster, or stop

Answer 13

Force

Question 14

What are the 3 KNOWN LAWS of Motion?

Answer 14

• Law of Inertia
• Law of Acceleration
• Law of Interaction

Question 15

According to The Law of Inertia,
“An Object at Rest will __________ and an Object at motion will ________”

Answer 15

-Remain At Rest
-Remain In Motion

Question 16

True or False: Objects with Greater the Mass have more Inertia
{Ex. A large truck, Bus, Etc.}

Answer 16

True

Question 17

According to the Law of Acceleration, “The Acceleration of an Object is __________ to the net force, and is __________ to the mass of an Object”

Answer 17

• Directly Proportional
• Inversely Proportional

Question 18

What Do we Mean By Directly and Inversely Proportional?

Answer 18

Directly Proportional means when One INCREASES, the Other One INCREASES aswell,
While Inversely Proportional Means When One INCREASES, the Other one DECREASES.

Question 19

What is the Known Formula for Finding FORCE?

Answer 19

F = ma

Question 20

Practice:
A car of mass 1,200 kg is accelerating at a rate of
3m/s^2. What is the force exerted on the car?

Answer 20

Given: m = 1200 kg
a = 3m/s^2
F=?
F = ma
F = [1200kg][3m/s^2]
F = 3600 kgm/s^2 or N
F = 3600 N

Question 21

What are The 2 FORCES under Non Contact Force?

Answer 21

• Gravitational Force
• Magnetic Force
