MOMENTUM

By:- Jihad A.

MASS AND INERTIA

Objects have many properties such as color, size, and

composition.

The mass of an object is the amount of matter in the object.

The weight of an object is related to the object’s mass.

The more mass an object has, the harder it is to start it

moving, slow it down, speed it up, or turn it.

This tendency of an object to resist a change in its motion

is called inertia.

• The momentum of an object in motion is related to how hard it is to

stop the object, and can be calculated from the following equation.

• Momentum ( in kg x m/s)= Mass (in kg) x Velocity ( in m/s) p=mv

MOMENTUM

The law of

conservation of

momentum states that in

a collision, the total

momentum of the

objects that collide is the

same before and after

the collision.

CONSERVATION OF MOMENTUM

The law of conservation of momentum enables you

to predict how the motions of objects will change

after a collision.

Sometimes, the objects that collide will bounce off

each other.

In other collisions, objects will stick to each other

after the collision.

The law of conservation of

momentum can be used to

determine how these objects

move after they collide. The

two objects must move in

opposite directions with the

same speed after the

collision.

COLLIDING AND BOUNCING OFF

When bumper cars collide, they bounce off

each other, and momentum is transferred.

Mass: The amount of of matter in the object.

Inertia: Tendency of an object to resist a change

in its motion.

Momentum: The measure of how hard it is to stop

the object, and it depends on the object’s mass and

velocity.

Law Of Conservation Of Momentum: The total

momentum of objects that collide is the same before

and after the collision.

VOCABULARY

Raise your hand patiently if you want to answer a question.

Color, size, and composition are properties of an

object.

3- What is the main similarity between velocity and

momentum?

Both velocity and momentum have a direction.
