Time Graphs
Distance Time Graphs
Shows how the distance travelled by an object changes over time
Speed = distance / time
Flat line - the object is stationary
Upward sloping line - object is moving away from the starting point
Downward sloping line - object is moving back towards the starting point
Velocity Time Graphs
Shows the speed (and direction) of an object changes over time
Flat line - the object is moving at a constant speed
Upward sloping line - the object is acceleration
Downward sloping line - the object is decelerating
Line at zero - object is stationary
Force Time Graphs
Shows how the force applied to an object and how long that force is applied for
Flat line - a constant force is being applied to the object
Upward sloping line - the force is increasing over time
Downward sloping line - the force is decreasing over time
Line at zero - no force is being applied
Downward movements lower the center of mass
