Slide 26

momentum

momentum

the mass times velocity of an object

p = m • v

Momentum = mass x velocity

(Kgrams) (meters/second)

the force of a moving body.

Slide 27

Momentum

Momentum

Higher mass higher momentum

Higher velocity higher momentum

Momentum = mass x velocity

p = m • v

Slide 28

momentum

momentum

includes velocity.

So, it has direction.

Momentum points in the direction of motion.

Slide 29

Conservation of momentum

Conservation of momentum

When objects collide, all of the momentum goes somewhere.

Slide 30

Conservation of momentum

Conservation of momentum

When objects collide, all of the momentum goes somewhere.

Slide 31

Conservation of momentum

Conservation of momentum

When objects collide, all of the momentum goes somewhere.

Slide 32

Conservation of momentum

Conservation of momentum

When objects collide, all of the momentum goes somewhere.

Slide 33

NEWTON’s

NEWTON’s

2nd Law of Motion :

An object that has a force acting on it will change its speed (accelerate).

Slide 34

NEWTON’s

NEWTON’s

2nd Law of Motion :

f = m•a

f = net force (newtons)

m = mass (Kilograms)

a = acceleration (meters/second2)

force = mass • acceleration

Slide 35

NEWTON’s

NEWTON’s

2nd Law of Motion :

f = m•a

acceleration of the club

force of the club

mass of the club

Slide 36

Net force is the total amount of Force (minus the forces that cancel each other out).

Net force is the total amount of Force (minus the forces that cancel each other out).

Force of gravity

Force of muscles

Net force

Slide 37

Balanced Forces

Balanced Forces

Unbalanced Forces

When the net force is Zero.

-> NO movement

When the net force is NOT Zero.

-> movement

Slide 38

2 Kg

2 Kg

?

Static Equilibrium Balanced forces

When all forces are balanced.

The net force is Zero.

There is NO movement.

3 Kg
