What is net force?
The sum of all the forces that act upon an object
What is the energy of motion called?
Kinetic Energy
A skateboarder travels 15 kilometres in 4 hours, calculate their average speed.
3.75 km/h
F=ma is associated with which Newton's Law?
Newton's 2nd Law
What is the object doing from 15 to 30 seconds?
It is travelling at a constant speed
What is inertia?
A property of matter by which it remains at rest or in unchanging motion unless acted on by some external force
What is the energy that is stored in an object due to its position above the ground?
Gravitational Potential Energy
A family drives from Brisbane to Lismore (198km) on a holiday, taking them a total of 2 hours and 20 minutes. What was their average speed in km/h?

Jimmy's legs apply a force to the ground, and the ground applies an equal and opposite reaction force that propels him into the air. This is an example of which Newton's Law?
Newton's 3rd Law
What is happening to the object from 30 to 45 seconds?
It is decelerating
What is the difference between speed and velocity?
Direction! Velocity requires a direction whereas speed can have any direction (Scalar vs Vector)
An air conditioner uses what form of energy?
Electrical Energy

What is the rate of acceleration from 5 to 10 seconds?
1.2 m/s2
m/s2 or m/s/s is the unit for what?
Acceleration
Food digesting in your stomach creates what form of energy?
Chemical Energy

940.8 J
Which of these items has more inertia when at rest: a Boeing 737 Aircraft or an E-Scooter
A Boeing 737 Aircraft
What is the total displacement of the object?
390m
Describe stopping distance.
Stopping distance is the distance covered between the time when the body decides to stop a moving vehicle and the time when the vehicle stops entirely. Stopping distance is the sum of reaction distance and braking distance.
Draw a diagram of a child going down a slide, list the energy present when they are at the top, middle and bottom of the slide.
Top = GPE
Middle = GPE + KE
Bottom = KE
An airplane is travelling at 80 m/s. What is this in km/h?
288 km/h
