Newton
What determines how fast a ball being kicked accelerates?
It's weight and the force applied to it.
Mr Reid weighs 90kg and is accelearting at 33m/s/s. What force is he going to run into Timmy with?
2970N of Force
If Mr. Reid is skydiving and is falling at a constant speed, are the forces acting on him balanced or unbalanced?
Balanced
Gas that traps heat. Methane, CO2, Nitrogen, etc.
What are the packets of information within a standard computer called?
Bits
Which of Newton's laws explain the recoil of a firing gun?
Newton's 3rd law
A car is travelling 100km/hr and slows down to 80km/hr over 10 seconds. What is the acceleration?
-0.56m/s/s
What is the law of conservation of energy?
Can't be destroyed or created.
How does the atmosphere influence global temperature?
Bounces radiation using clouds, holds heat in gases.
What are the packets of information within a quantum computer called?
Qubits
What is inertia?
The tendency for an object to resist change in motion.
What is the value of 'g'?
9.8N or 9.8m/s/s
How can you determine whether an object is accelerating using free-body diagrams?
If the forces are unbalanced, they are accelerating.
As ice melts, the less salty water forces the salty water below to move and therefore, affects the ocean currents coming from the arctic/antarctic.
What affects weather?
Bunch of stuff.
Why does a bus take longer to slow down compared to a car?
Newton's 2nd law.
What is the difference between velocity and speed?
Velocity has magnitude and direction (vector) while speed only has magnitude (speed)
What is the Earth-Solar energy balance?
The balance between the solar energy received and the energy emitted from the earth.
What are 3 ways in which animals can react to climate change?
Migrate, adapt, die.
What is a quantum computer? How is it different from a standard computer?
Quantum stuff
What are 3 safety features of a car that use Newton's laws to save lives? Explain.
Crumple zones, seatbelts, air bags.
Crumple zones distribute energy into the vehicle, seatbelts reduce the effect of inertia, air bags also do the same.
Draw what acceleration would look like on a graph
Correct drawing should have an exponential curve.
Describe why boats are quicker on ice in Minecraft using free body diagrams and Newton's 2nd law.
Ice is less friction which means less energy required.
What are 4 ways in which we can observe climate change?
Global temperature, ice caps melting, ocean currents, ocean temperature.
Explain how the double-slit experiment influences our understanding of Light Wave-Particle Duality?
Smart stuff
