A toy truck is at rest on the floor. Is the force balanced or unbalanced? Why?
Balanced. The Truck is at rest, so there is unbalanced forces acting on it.

Length divided by time (L/T) allows us to calculate this...
What is speed or velocity?

The diagram shows a boat moving north in a river at 3 m/s while the current in the river moves south at 1 m/s. How will the boat be affected if it enters a part of the river where the current is moving south at 2m/s?
What is the boat will decrease it's speed to 1m/s?

How does increases the mass of an object affect that object's momentum?
It increases the objects momentum
300
mass * velocity = [?]
What is momentum?
300
At which point would the ball have the most kinetic energy?
What is point B?

While mining through the rocky tunnels, Steve mines westward with a pickaxe weighing 30 Iron Ingots. Using this pickaxe Steve mines a tunnel with a distance of 50 Blocks in a period of 5 Creeper Explosions.
What is Steve's Velocity? (USE UNITS!)
What is 10 Blocks / Creeper Explosion West?
400
The property of resisting a change to your present velocity
What is Inertia?

Using the Law of Conservation of Energy explain what happens as a roller coaster goes down a hill?
Energy is converted from Potential Energy to Kinetic Energy.

These three vehicles shown below are traveling at a constant speed of 15 m/s, are any of the vehicles accelerating? why or why not?
The truck is accelerating, as it is turning, therefore it's velocity is changing.
