  • This video introduces and explains displacement-time graphs and velocity-time graphs for A Level Physics.
    Developing your GCSE knowledge of distance-time and speed-time graphs with your new knowledge of their vector equivalents. Displacement is the vector equivalent of distance and velocity is the vector equivalent of speed. The gradient of a displacement-time graph is equal to the velocity of the object. The area underneath a velocity-time graph is equal to the total displacement of an object. We can also use a velocity-time graph to produce an acceleration-time graph.

    Hey Steve! Me and my friend have had a disagreement. He is saying that your acceleration time graph is wrong. Is he correct? He is saying that it is nota line but acceleration turns positive when the object starts to fall back down.

    Firstly, your videos are great and incredibly helpful!
    Secondly, I have a little question: For the three graphs drawn at the end, is the object constantly decelerating?
    Thanks in advance :)

    • @PhysicsOnline
      @PhysicsOnline  8 ปีที่แล้ว +5

      +Jack Devin Yes it is. If we say that upwards in the positive direction, then as it is always accelerating down due to gravity then it always has a negative (and constant) deceleration.

    Hi, how do you convert between a velocity time graph, and a displacement time graph. EG if they give a displacement time graph and say convert it into a velocity time graph, Would I have to calculate the gradient of the displacement time graph then plot a straight line (0 gradient) on the velocity time one?

    i am always a big fan your videos,
    And, got a little question: why do we take the upward velocity as positive most often, even though the ball is being thrown against the direction of gravity?
    whay dont we take up wards as negative and downwards as positive ??

    • @PhysicsOnline
      @PhysicsOnline  8 ปีที่แล้ว +3

      There is no reason for it, you can make whichever direction you like as the positive direction.

    @samsloan8513 5 ปีที่แล้ว +1

    it is not its gravity which is the force acting on it to cause it fall back down but the objects weight which is equal to its mass x gravity

      velocity is a vector, so it has a magnitude and direction. If say a car is going straight it has a positive velocity, if it reverses it has a negative velocity

    3:48 why does it have the highest possible velocity at the start ?

    • @mga9478
      @mga9478 5 หลายเดือนก่อน

      Difference is because in the first Velocity Time graph the man is moving at a constant velocity. Straight line… however with a ball, it loses energy due to Gravity, so is is not in a straight line. Velocity is constantly decreasing over time, hence highest velocity is at the start.
