# Force and Motion

## Teks

Readiness standard 6.8c Calculate average speed using distance and time measurments.

Supporting Standards:

6.8 B Identify and describe that changes in position, direction and speed of an object when acted

upon by an unbalanced force.

6.8 D Measure and graph changes in motion.

## DQ

Using examples from the recently completed Rio Olympics, how can your team show and explain the relationship between force and motion?

## ??Need To Knows??

what is force?

what is motion?

how can we demonstrate Newtons first law of motion?

what is Newton's 1st law ?

what is Newton's second law?

what is Newton's third law?

How are force and motion related?

How does force and motion apply in the olympics?

How can you show force in the olympics?

How can you show motion in the olympics?

## Newtons laws of motion

FIRST LAW-An object at rest will remain at rest unless acted on by an unbalanced force.

SECOND LAW-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

THIRD LAW-For every action there is an equal and opposite re-action.

## NEWTONS FIRST LAW

in soccer the ball sits there until something acts upon it, like if someone kicks it.

just like football the ballis on a crate or sitting there until someone acts upon it with a force.

## what is force?

strength and energy able to move an object.such as push or pull

Key New Vocabulary

Average Speed Total distance travelled by an object over the total time.

Distance The space between two objects or points. (physical property)

Time The duration of an event or action over a certain period (of time).

## what is motion?

an object in motion is like when you are riding a bike and it is moving

## Newtons second law

when a car is going 10 miles per hour (m/h) when someone presses on the gas peddle

it accelerates. The mass is the car.

## force and motion in the olympics

One of the competition is Discus it is a track and field competition. You use all your force to throw the discus, and you use your motion to turn and throw it.

## Newtons third law

Every action there is an equal and opposite reaction. like if you throw a ball at the wall the ball is pushing on the wall but the wall has an equal and opposite push causing the ball to bounce off

## Calculating Speed

Speed equals distance divided by time

## THANK YOU FOR WATCHING!!!!

thank you for watching our presentation

## finding the speed

you divide distance divided by time to find speed.
