Motion and Speed
Speed is equal to distance divided by this.
What is time?
Acceleration is the rate at which this changes.
What is velocity?
Force is simply one of these two things.
What is a push or pull?
The unit of measure for force.
What is a Newton?
The formula to find force of gravity.
What is Force = mass x gravity?
Speeding up, slowing down, or changing directions.
What is acceleration?
The unit of measure for acceleration.
What is m/s/s (meters per second squared)?
The net force on a 2 kg object with an acceleration of 8 m/s/s.
What is 16 Newtons?
An object at rest tends to stay at rest is part of this law of motion.
What is the 1st Law of Motion?
The rate of acceleration of gravity on Earth.
What is 10 m/s/s?
The velocity of an object that travels 100 meters in 5 seconds.
What is a 20 m/s?
The acceleration of a car that goes from rest to 20 m/s in 5 seconds.
What is 4 meters per second per second?
The sum of all forces acting on an object.
What is the net force?
For every action there is an equal and opposite reaction is this law of motion, according to Newton.
What is the 3rd Law of Motion?
When taken to the moon from Earth, an object's weight will change, but this will not.
What is mass?
An object that is moving faster will have a greater one of these on a position vs. time graph.
What is slope?
The amount of time it takes for an object to go from 12 m/s to 20 m/s if it accelerates at a rate of 2 meters per second per second.
What is 4 seconds?
This force always acts in the opposite direction of an object's motion.
What is friction?
The tendency of an object to resist changes in motion.
What is inertia?
If gravity is the only force acting on an object, the object is considered to be in this.
What is free fall?
A quantity that has both size and direction.
What is a vector?
The acceleration of a car that goes from 5 m/s to 14 m/s in 3 seconds.
What is 3 meters per second per second?
These are the three types of field forces.
What are gravity, magnetism, and electricity?
In order for there to be acceleration, forces must be this.
What is unbalanced/unequal?
The conditions necessary for a bowling ball and a feather to fall at the same rate.
What is a vacuum?
