Aims…
1.3 plot and interpret distance–time graphs
1.7 plot and interpret velocity–time graphs
1.8 determine acceleration from the gradient of a velocity–time graph
1.9 determine the distance travelled from the area between a velocity–time graph and the time axis.
1.4 know and use the relationship between average speed, distance moved and time: average speed = distance moved/time taken
1.5 practical: investigate the motion of everyday objects such as toy cars or tennis balls.
1.6 know and use the relationship between acceleration, velocity and time:
acceleration = change in velocity/time taken OR a = (v – u)/t
1.10 use the relationship between final speed, initial speed, acceleration and distance moved:
(final speed)2 = (initial speed)2 + (2 x acceleration x distance moved) OR v2=u2 + (2as)

Draw a tangent to the curve in order to calculate the gradient of the
curve at that point. This will give us the reaction rateFlipped Classroom - Tangent Lines

Tangents to a Curve - GCSE Physics
This video introduces tangents to a curve. This is slightly more complicated than calculating the gradient of a straight line. It involves the same method of calculating the gradient of ...a straight line but with an extra step.
Sometimes you need to work out the slope at a particular point on a curve:
- Carefully draw a straight line with a ruler that just touches the curve
- Work out the gradient of this straight line in the usual way

When do we say that an object is accelerating? What happens to the velocity of an object when it accelerates or when it is in motion? Is acceleration scalar or vector? or What is acceleration?
Watch this video to know the answers!
Acceleration is the rate of change of the velocity of an object with respect to time.
Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation a = Δv/Δt.

Ethanol Velocity of a lit flame can be worked out using heatproof mats and a pipette of ethanol. You simply pour around 1m over the tiles in a thin line ...and set light.
OR
Use a copper pipe with a slit cut and two rubber bungs. You need to try and just get the right amount, so a few pipettes in a cold tube. The tube temp puts out the flame and it travels in a pulse. You can send mutiple pulses down. If you do it whilst hot, you have a fire risk! Also not enough ethanol will mean it will not travel. You need the fluid to pick up the flame motionShow More
