science test N2L Flashcards
how fast an object is moving in a specific direction. Measured as distance divided by time. Use equation V = d/t
Velocity
a change in velocity over time. Unit = m/s/s
acceleration
forces that are either not equal in strength or direction (DOES cause a change in motion)
Unbalanced force
the force of attraction between any 2 objects
gravity
Units of measurement for Acceleration
m/s/s
Formulas for Acceleration (there are 2)
F=MA or a = Vf-Vi / Tf-Ti
The acceleration of an object is dependent on two variables–(1) the mass of the object and (2) the net force acting on the object
N2L
Greater the force, _________ the acceleration
greater
Greater the mass, the ____________ the acceleration for the given force.
less
Acceleration is inversely proportional to what?
mass
A large mass requires a proportionally ______ force to achieve the same acceleration
larger
Acceleration is the result of _________ forces?
unbalanced
If there is NO acceleration, the net force must be ______.
0
