A Formula 1 Margarine Tub I think the following factors will affect the speed at which the tub travels: * The weight of the tub * The amount of force used to propel the margarine tub * The friction caused by the surface the tub travels on * The surface area of the margarine tub I have chosen to investigate how the amount of force used to propel the margarine tub will affect the speed. ...read more.


I believe the speed of the margarine tub will increase as the force does because the amount of energy input has increased therefore the elastic potential energy is increased and when the elastic band is released there is a higher amount of kinetic energy transferred and the tub will go faster. ...read more.


This proves that speed is affected by force, mass and distance.

Here's what a teacher thought of this essay

3 star(s)

This is a good start to a report, although it is very brief.
1. The inclusion of the equations and diagrams is good.
2. The table of results is well presented.
3. The report is lacking a general structure. Use subheadings to make sure that all aspects are covered.
4. The report is missing several aspects including a graph, an analysis and an evaluation.
*** (3 stars)

    Only one variable, mass or surface used, will be changed at any one time, the remaining variables, surface area of the block of wood, and direction, will remain constant, to respect fair testing. Apparatus: -10g, 25g, 50g, and 100g weights -A pulley -Sand paper (P60E), and a plank of wood -A rectangular block of wood (325g)

  1. Investigation into Friction.

    Static friction is when the two surfaces are not sliding over one another, but are stationary. The coefficient of static friction is higher than that of dynamic friction, because once the force of friction is overcome, which takes quite a lot of effort, comparatively little force is needed to keep the surface in motion, and overcome the force of friction.

  1. Investigating Friction

    Set up the apparatus like the above diagram (see the plan), with a 100g mass on the block (to see how much force we need to move 100g by using the metal iron block). Make two tables to record two kinds of block materials (the force needed for each material block will be different as my hypothesis said).

  2. Report on Newton's laws of motion

    mass requires a force of one Newton (N). However, if the friction were 4 N, a force of 5 N must be applied to give the same acceleration. The resultant force is 5N (applied) -4N (friction) which equals to 1N (bookrags, n.d.).
