motion

The rate of change of velocity of an object over time. It is a vector quantity, indicating both the magnitude and direction of change.

acceleration

power that can change in an object or systems.

force

statement about scientific thing that is out there and always occurs under the right conditions.

law

measurement of the amount of matter somthing has.

mass

the process act or result of changing place or positions

motion

the earth it orbits around and you dont feel it

motion that you can not see moving

stay in place

object in motion is moving in relation to an object that appears to …

moving

when an object chnages positions over time relative to a refrence point, the object is ..

Reference point

determining motion, the surface of earth is a common.

Their stable, well-defined structures help determine distance and direction within a given area.

why are building useful reference point

yes, if an object is in motion if it changes positions it can be used as a reference point.

can a moving object be used as a reference point.

Time

the speed of an object depends on the traveled and the … taken to travel that distance.

Matter.

the SI unit for speed is

To compare and see what one is faster

why is it useful to calculate average speed

total distance divided by total time.

how to calculate average sppeed

The average speed will change.

How does the distance traveled in one hour usually compare with the distance traveled in other hours

No, unless the speed and direction are the same.

Two lines on a graph showing speed. One line represents speed per hour, the other shows average speed. Will both lines be exactly alike?

They could be going in different direction.

Why wouldn’t birds end up at the same destination if they are flying at the same speed?

Velocity includes direction, while speed does not.

what is the difference between velocity and speed.

You add the speed of both than keep the same direction.

How to calculate the resultant velocity of two velocities in the same direction.

You would subtract the smaller one with the larger velocity, keeping the direction of the larger.

how would you calculate the resultant velocity of two velocities in opposite direction

yes you are accelerating when you are changing direction you are changing velocity

If your speed is not changing, but your direction is changing. Are you accelerating?

positive

Another name for acceleration is, which velocity increases is… Acceleration

deceleration and negative acceleration

What are two common terms for decrease in velocity?

You would take the final subtracted by the beginning divided it by the time.

Write a mathematical formula for calculating average acceleration.

The velocity is changing overtime

A speed monitor shows what cyclist is going one M/S the first second 2M/S the 2nd second and 3MS the third second as a second continued straight south how do you know the circular is accelerating?

X= time, Y= speed

I would acceleration be shown on a graph

The graph will have an upward representing the roller coaster, traveling down the hill, showing the change of velocity

A graph shows a roller coaster increasing its velocity for the first eight seconds as it goes down the hill, with a graph showing an upward slope, representing the roller coaster traveling downhill.

Even if it slows down or speed up, it will always be accelerating.

As long as something travels in a circle it always accelerates
