You can use distance–time graphs to calculate speed / acceleration. The steeper the gradient, the slower / faster the speed / acceleration. You can use velocity-time graphs to calculate speed / acceleration. The steeper the gradient, the slower / faster the speed / acceleration. Q) A police car travels 6000 metres in 500 seconds. Calculate the average speed with units. Q) An object speeds up from 2 m/s to 6 m/s in 2 seconds. Find its acceleration with units.
2
Falling objects L.O.: Use the equation weight = mass x gravitational field strength. Describe the forces acting on a falling object. Explain what terminal velocity is.
3
In pairs, discuss ( 2 minutes): What is the difference mass and weight. Would your weight in the Moon be the same? Why clip
4
The weight of an object is the force of the gravity on it. The mass of an object is the quantity of matter in it. weight = mass x gravitational field strength.
5
motion of a parachutist
7
If an object falls in a fluid, the fluid drags on the object. The drag force increases with speed. If the fluid is air, the drag force is called air resistance.
8
To do: 1) Workbook pages 63, 64 2) Worksheets.
