Practicals - use of light gates, weights and trolleys to investigate the link between force and acceleration. Use of data from stretching an elastic band with weights to plot a graph to calculate the work done. Be able to apply the following equations: Practical - measurement of work done by learners lifting weights or walking up stairs.

Demonstration of the behaviour of colliding gliders on a linear air track. Common misconceptions - the concept of potential difference may be very difficult to grasp. Having looked at the nature of matter, we can now introduce the idea of fields and forces causing changes.

Investigation of the magnetic field around a current-carrying solenoid using plotting compasses. Practical using light gates, weights and trolleys to investigate the Ocr science papers gcse between force and acceleration.

This develops the idea that force interactions between objects can take place even if they are not in contact.

Demonstration of, and uses of a Van de Graaff generator. Record and plot results. Investigation of the brightness of bulbs in series and parallel. You should be aware of moments acting as a turning force.

Use of a water rocket to demonstrate that the explosion propels the water down with the same momentum as the rocket shoots up. Discussion of why charged balloons are attracted to walls. You should have been introduced to the measurement of conventional current and potential difference in circuits.

Practicals - use of light gates, weights and trolleys to measure momentum of colliding trollies. Practical - construction of simple motors. The electrical current, potential difference and resistance are all covered in this topic. Practical - comparisons of behaviour of springs and elastic bands when loading and unloading with weights.

You may have difficulty understanding the concept of field line density being an indicator of field strength. Calculating resultant forces using vector diagrams and work done Revision Notes Measurement of the velocity of ball bearings in glycerol at different temperatures or with ball bearings of differing sizes.

The generation of charge is considered. Charge is a fundamental property of matter. Use of suspended magnets to show attraction and repulsion. You should have been introduced to magnets and the idea of attractive and repulsive forces.

Common misconceptions You may have difficulty classifying materials as insulators or conductors. Use of a charged rod to deflect water or pick up paper.

Calculating resultant forces using vector diagrams and work done Revision Notes P2. They can also still result in an object changing shape or motion.
