7.2 Acceleration Flashcards
1
Q
What is the definition of acceleration?
A
» Change of velocity per unit time
2
Q
What are the units of acceleration?
A
» ms^-2
3
Q
What is uniform acceleration?
A
» Where the velocity of an object moving along a straight line changes at a constant rate
» Acceleration is constant
4
Q
What is the formula for acceleration by using the gradient of a velocity time graph?
A
» a = (v-u)/t
» v = u + at
5
Q
What is non-uniform acceleration?
A
» Where the motion of an object changes at a varying rate
6
Q
How can you find acceleration when acceleration is non-uniform?
A
» Draw a tangent at that specific time
» Calculate the gradient on the velocity time graph
