LAWS OF MOTION BY GROUP 1

Pre-Test

Answer the following questions in a ½ crosswise.

1.)What law is natural the tendency of an object to

maintain a state of rest or to remain in uniform motion?

INERTIA

2.) What is Motion?

The action or process of moving or being moved!!

3.) Who is the Scientist that DEFINED inertia as

the tendency of an object to maintain its initial state of motion?

GALILEO GALILEI

4.) Does Mass effect an acceleration of an

Object?

OFCOURSE

5.) What branch of science studies the 3

laws of motion?

DYNAMICS

6.) Who is the English scientist and

Mathematician did further studies on the ideas of Galileo Galilei and created the 3 laws

of motion?

ISAAC NEWTON

7.) What Law of motion have this definition:

“For every action, there is an equal and

opposite reaction”

LAW OF INTERACTION

8.) What law of motion is the property of

matter that causes a body to resist changes in its state of motion?

INERTIA

1st Law of motion: INERTIA

*Objects at rest- “an object at rest will remain at rest unless an outside force will cause it to move”

Ex.)

A soccer ball will remain at rest until it is kicked.

The cart standing still in a grocery store has inertia at rest it will move unless someone will push or pull it.

1st law of motion: INERTIA

Objects in motion- “an object at motion continues to move in the same direction unless an outside force will stop it”

Ex.)

A person stops pushing a cart and it stops moving

2nd Law of motion: ACCELERATION

“the acceleration of an object is directly proportional to the force applied and inversely proportional to the mass of an object”

*the greater force applied the greater the change in motion of an object.

*the greater the mass the slower the acceleration of an object.

Law of Acceleration Formulas

Acceleration (a)= Force/Mass

Force (F)= Acceleration x Mass

Mass (m)= Force/Acceleration

FA M

3rd Law of motion: INTERACTION

“FOR EVERY FORCE OF ACTION, THERE IS AN EQUAL OR OPPOSITE REACTION”

EX.)
