Motion and Speed
The formula for speed.
What is speed = distance divided by 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?
A change of position.
What is motion/movement?
The unit of measure for acceleration.
What is m/s/s (meters per second squared)?
Gravity and magnetism are both this type of force.
What is a non-contact force?
An object at rest tends to stay at rest is part of which of Newton's laws of motion.
What is the 1st Law of Motion?
The rate of acceleration of gravity on Earth.
What is 9.8 m/s/s?
Constant speed looks like this on a graph.
What is a straight line?
Acceleration in a circular motion.
What is centripetal acceleration?
The combination of all forces acting on an object.
What is 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?
An object traveling around another object is in this.
What is orbit?
Velocity requires these two parts.
What is speed and direction?
The formula for acceleration.
What is acceleration = final velocity-initial velocity divided by time?
Friction is this type of force.
What is a contact force?
The tendency of an object to resist change.
What is inertia?
If gravity is the only force working on an object, the object is in this.
What is free fall?
A quantity that has both size and direction.
What is a vector?
The acceleration rate of a car that goes from 0-60 miles per hour in 4 seconds.
What is 15 miles per hour per second?
The formula to find force on an object moving horizontally.
What is Force = mass x acceleration?
In order for there to be movement, forces must be this.
What is unbalanced/unequal?
The setting that must occur for a bowling ball and a feather to fall at the same rate.
What is a vacuum?
