Kinematics Flashcards
1
Q
Define distance.
A
Total length travelled by a moving body regardless of the direction it travels.
2
Q
Define displacement.
A
Displacement of a body is the distance from a reference point in a specific direction.
3
Q
Define speed.
A
Speed is defined as the rate of change of distance.
4
Q
Define velocity.
A
Velocity of a body is defined as the rate of change of displacement.
5
Q
Define acceleration.
A
Acceleration of a body is defined as the rate of change of velocity.
6
Q
State the 4 kinematics equations regarding the values of u, v, s, a and t. (includes the 2 equations in the formula list)
A
v = u + at s = ut + ½at^2 v^2 = u^2 + 2as s = ½(u + v)t
