10 Newtons per kilogram
What is the gravitational force on earth?
Parallel and series
Two different ways of wiring up a circuit
km/h, m/s or mph
The units for speed are..
Points to north
A compass needle
What is a discrete function?
Non-linear. Not continuous. Limited.
air resistance
What is the force that slows a vehivle down?
=Resistance
voltage divided by current
mean or average speed
The total distance travelled by the total time taken.
Iron
A material that is attracted to a magnet
3rd
Another name for a fulcrum
A pivot
....depends on these 3 things -
The material from which it's made, the length, the thickness
Resistance
distance/ time
speed =
By increasing the number of turns on the coil, increasing the current or using an iron core
You can increase the strength of an electromagnet by...
Is the equation x+y=-20 discrete or continuous?
Continuous because it forms a line and includes negative #'s, as well as decimals.
The clockwise moment is equal to the anticlockwise moment
When a force is balanced
The bulbs will share the current and be dimmer than if they were on their own.
If bulbs are wired up in series
A straight line on a distance/time graph
When the car is stationary there is.....
Is the same as that of a bar magnet
The magnetic field around an electromagnet
2nd one
The greater the moment
The longer the distance from the pivot
The current splits at the junction of 2 wires
in a parallel circuit
The speed of a faster car compared with a slower car
Relative speed is...
The way the current is flowing through the wires in the coil
