P2 U2 Motion
- Distance-time graphs
- The gradient of the
line on a
distance-time graph
represents an
object's speed.
- The steeper the line
on a distance-time
graph, the greater the
speed it represents.
- We can use graphs to
help us describe the
motion of an object.
- A distance-time graph shows
the difference of an object from
a starting point (y-axis) against
time taken (x-axis)
- The speed of an
object is the
distance travelled
each second
- The gradient of the line on a
distance-time graph
represents speed. The steeper
the gradient, the greater the
speed.
- If an object is
stationary, the line
on a distance-time
graph is horizontal.
- If an object is moving at a
constant speed, the line on
a distance-time graph is a
straight line that slopes
up.
- The gradient of the
line on a
distance-time graph
represents an
object's speed.
- Velocity and acceleration
- The velocity of an object is its speed in a given direction.
- If the object changes direction it changes velocity, even if its speed stays the same.
- If the velocity of an object changes, we say that ut accelerates.
- If the value calcualted for acceleration is negative, the body is decelerating (slowing down). A deceleration is the same as a negative acceleration.
- The velocity of an object is its speed in a given direction.
- Velocity-time graphs
