The unit conversion acronym
what is KHDUDCM?
The unit velocity is measured in
m/s
Formula for acceleration
what is change in velocity over change in time?
The rate gravity accelerates at
What is newtons?
The definition of scalar
What is a value described by magnitude only?
Is velocity a vector or scalar?
Vector
The unit acceleration is measured in
What is m/s/s?
The vertical velocity does or does not change as an object falls?
Does
Out of mass and weight, which one depends on gravity?
Weight -- since it is a force
The definition of vector
What is a value described by magnitude and direction?
Someone travels 4m in 2s, the velocity is...
2 m/s
The meaning of a horizontal line on a velocity vs. time graph
What is constant velocity
An object lauched and one dropped will or will not hit the ground at the same time?
Will
If an object has a high coefficient of friction it means ___. Give an example of an object with a high coefficient of friction.
The object has a lot of friction. An example is sandpaper.
50,000 mm converted to km
What is .05 km?
The object is moving at a constant velocity
The acceleration of a dog traveling at 4 m/s for 2 seconds
What is 2 m/s/s?
Affects how long it takes an object to hit the ground (ignoring air resistance)
What is height?
The definition of net force
What is the total of all the forces?
The definition of displacement
What is a vector quantity that tells how far an object has traveled from its starting point?
What does a horizontal line on a distance vs. time graph mean?
at rest/not moving
To represent no motion on a velocity vs. time graph
What is a straight line at 0?
Horizontal motion of a projectile does or does not affect the downward motion of the projectile?
Does not
Based on its net force, how can you tell when an object is in equilibrium
The net force is equal to 0
