Motion
The location of an object.
What is position?
A measure of how much an object's position changes over time.
What is speed?
A measurement that combines speed and direction.
What is velocity?
An example for a proper label for acceleration.
What is
m/s/s OR m/s2 OR km/h/s OR mph/s
This is the product of mass and velocity.
What is momentum?
A change in a position over time.
What is motion?
The measurement of speed at one moment in time.
What is instantaneous speed?
The units that the abbreviation "mph" stand for.
What is miles per hour?
A word that means the same thing as negative acceleration, or slowing down.
What is deceleration? (or decelerate)
This is the tendency of an object to resist a change in motion.
What is inertia?
The two parts of motion.
What are distance and direction?
A measurement of speed calculated over an entire trip.
What is average speed?
A word for how an object's velocity changes over time.
What is acceleration?
If the speed of an object does not change, it could still be accelerating. This is possible because it could be changing THIS instead of changing speed.
What is changing direction?
Momentum must be stronger than inertia in order for an object to do this.
True or False: Frames of reference can move
What is True
(for example: the inside of a moving car)
The two measurements that are needed to calculate average speed using the speed formula.
What are distance and time?
Two components of velocity that could change when an object accelerates.
What are speed and direction?
This word means the distance that you travel per second, (or per minute, or per hour).
What is speed?
This is the formula for momentum.
What is . . .
momentum = mass X velocity
A group of objects from which you can measure position or motion.
What is a frame of reference?
The formula for calculating average speed.
What is average speed = distance / time ?
The formula for acceleration.
What is
acceleration = change in speed/time ?
This word means how much you speed up, slow down, (or change direction) per second.
What is acceleration?
These are two examples of labels for momentum.
What is . . .
kg m/s OR g m/s
