Distance
An amount of space between two things or people.
What is distance?
A result of a force moving an object a certain distance.
What is work?
Tommy does 15 Joules of work to push the pencil over 1 meter. How much force did he use?
15N
Any kind of push or pull on an object.
What is force?
The rate at which an object is moving at a given moment in time
What is instantaneous speed?
A place or object used for comparison to determine if an object is in motion
What is reference point?
Unit of measurement for work.
What is joules?
Angela uses a force of 25 Newtons to lift her grocery bag while doing 50 Joules of work. How far did she lift the grocery bags?
2m
When a force is enough to move an object from its original position, this is what happens.
What is work?
A variable that tells you both speed and direction.
What is velocity?
A change is position over time.
What is motion?
This must be applied in order for work to be completed.
What is force?
Alex applies 350 N of force to move his stalled car 40 m, how much work did Alex do?
14,000 joules
SI unit of force.
Newton
Formula for speed.
Speed= Distance / Time
Distance and direction of an object's change in position from the starting point.
What is displacement?
Formula for work.
W = FxD
If it takes 500 Joules of work to move your best friend 10 m, what force was needed?
50N
Formula for force
F = W/D
A measure of the change in velocity during a period of time.
What is acceleration?
