Kinematics Flashcards
Distance is…
the space between two fixed positions.
Displacement is…
the distance between two fixed points and the direction from one and other.
Speed is…
the rate of change of distance.
Velocity is…
the rate of change of displacement.
Acceleration is…
the rate of change of velocity.
Displacement-time graph:
-the gradient is the velocity
Instantaneous speed is speed…
at a certain point.
Velocity-time graph:
- gradient is acceleration
- area is displacement
V=
u + at
s=ut +
0.5 x at squared
s=
0.5 x (u+v) x t
v2 =
u2 + 2as
Trajectory is…
the path of any moving object.
A projectile is an object…
that is given an initial force then allowed to move freely through space.
A parabola is a name…
given to the shape of the curve, a projectile follows when gravity is the only force acting on it.
