16
Q

the laws of physics simply give us the ability to predict/calculate different physical phenomena but these are intelligent estimations only.

A

Principle of “idealized models”

17
Q

a small part of the big universe on which the scientists choose to
focus their study on, wherein some factors in the real world are excluded in order to make the study more focused and easier.

A

Idealized model

18
Q

This individual developed the laws of motion to provide conceptual and mathematical foundations for the interaction of objects on Earth and beyond. The central theme of these laws is how forces affect the state of motion of any object.

A

Sir Isaac Newton

19
Q

an object at rest will remain at rest, an object in motion continues in motion with the
same speed and the same direction unless acted upon by an unbalanced force.

A

Law of Inertia - the first Law of Motion

20
Q

the push or pull upon an object resulting from its interaction with
another object.

A

Force

21
Q

Force is measured in terms of?

A

Newton(N); 1N=1kg. m/s2

22
Q

the two equal forces that act on an object in opposite directions; the sum of these forces is zero, thus, there is no change in motion

A

Balanced force

23
Q

equal forces in opposite directions produce no motion

A

Balanced force

24
Q

The sum of all the forces along
the x-axis is zero.

A

∑Fx = 0

25
Q

The sum of all the forces along
the y-axis is zero.

A

∑Fy = 0

26
Q

one of the two forces
acting upon an object is greater than the other; the object moves in the direction of the greater force; the sum of these forces
is not equal to zero. Thus, there is a change in motion.

A

Unbalanced force

27
Q

Unequal opposing forces produce an ? causing motion

A

Unbalanced force

28
Q

Acceleration is produced when a force acts on a mass. The greater the mass (of the object being accelerated) the greater the amount of force needed (to accelerate the object).

A

Law of Acceleration - the Second Law of Motion

29
Q

What is the equation for finding the total force?

A

∑F = ma

30
Q

F in the equation is equal to?

A

total force - in Newton (N)

31
Q

m in the equation is equal to?

A

the mass of an object (kg)

32
Q

a in the equation is equal to?

A

acceleration (m/s2)

33
Q

It is directly proportional to the net force and inversely proportional to the mass.

A

Acceleration

34
Q

For every action, there is an equal and opposite reaction.

A

Law of Interaction - the Third Law of Motion

35
Q

What are the Three Laws of Motion? (in order from first to third)

A

Law of Inertia, Law of Acceleration, Law of Interaction

36
Q

What are the two types of forces under the Law of Inertia?

A

Balanced and Unbalanced forces
