Describing Motion
The total amount someone travelled.
What is distance?
The push or pull on an object.
The International System of Units (SI unit) for the Joule (J).
Energy cannot be created nor destroyed.
The slope in a distance-time graph.
What is velocity?
This quantity involves both speed and direction.
What is velocity
This is done on an object when force is applied to move something some distance.
What is work?
The ability to do work.
What is energy?
No energy transformation is 100% efficient.
The slope of a velocity-time graph.
What is acceleration?
Total distance travelled divided by time.
What is speed?
The weight of someone with a mass of 60kg on Earth.
Energy stored due to an objects position.
What is gravitational potential energy?
The type of energy that is often lost in energy transformations.
What is thermal or heat energy?
How you find the displacement from a velocity-time graph.
What is the area under the graph?
A runner completes a lap on a track (ends where they started), this is their displacement.
What is zero?
The amount of work it takes to move an object 10 m with a force of 50 N.
What is 500 J?
Energy of an object due to it's motion.
What is kinetic energy?
The efficiency of a machine that converts 1609 J of chemical energy into 1050 J of kinetic energy.
What is 65%
The distance-time graph of an object in positive uniform motion.
What is a straight positive sloped line?
This quantity is represented by the area of an acceleration vs. time graph.
What is velocity?
The area under the line of a force-distance graph.
What is work?
The total energy of a 60 kg object rolling down a 10 m hill at 5 m/s.
What is 6,636 J?
The 4 energy transformations that happens in a coal plant.
What is chemical energy to thermal energy to kinetic energy to electrical energy.
The velocity-time graph of an object that starts out with positive uniform motion then slows to a stop.
What is a flat line then a straight negative slope?
