9
What is the BEST definition of acceleration?
change in speed or direction
decreasing speed
stopping
increasing speed
10
Why do we experience different seasons throughout a year?
Because of the TILT of Earth's axis as it REVOLVES around the Sun
Because of our distance from the Sun
Because of Earth's rotation
Because of Mother Nature
11
How would you calculate the
acceleration
of an object when given its
force (N)
and
mass (kg)
Force plus mass (a = f + m)
Mass divided by force (a = m/f)
Force divided by mass (a = f/m)
Force times mass (a = f x m)
