Acceleration Flashcards
What is the meaning of acceleration?
How quickly the velocity is changing.
What is the equation for acceleration?
Acceleration (m/s2) = (final velocity - initial velocity (m/s)) / time (s)
What is negative acceleration called?
Deceleration
What must you do in a question asking for acceleration when you don’t know the speed?
Use your typical speeds knowledge to estimate.
What is uniform acceleration also known as?
Constant acceleration.
What is the equation for uniform acceleration?
(Final velocity)^2- (Initial velocity)^2 = 2 x acceleration x distance
What is free fall?
Acceleration due to gravity.
What is free fall’s gravity equal to?
10m/s^2 near the Earth’s surface
What is free fall the same as?
Gravitational field strength.
What is the acceleration of an object which is free falling?
10m/s^2
