5 FORCES Videos questions on the CD ROM Combinations of forces can have all kinds of effects. pushing pulling turning WHAT ARE FORCES? A force is a push or a pull. The way that an object behaves depends on all of the forces acting on it. A force may come from the pull of a chain or rope GCSE Science Questions Pack 5 Pearson Publishing 01223 350555 9 Unit 3 Equilibrium and Turning Forces The centre of gravity of an object is the point through which the whole weight of the object seems to act. A metre stick supported above its centre of gravity will be level - in equilibrium; but if it is held somewhere else it will be. A moment is the turning effect of a force. Moments occur when forces cause objects to rotate about some pivot. The size of the moment depends upon: The size of the force. The distance between the force and the pivot. The moment of a force is given by the equation: Moment = Force × perpendicular distance from the pivot Effects of forces Turning forces are found in many everyday situations and are essential for machines to function. Levers and gears make use of these turning forces to provide an advantage
A moment is a turning effect of a force and you come across them every day of your life. For the physics GCSE, you need to know some examples of forces that create turning effects, how the principle of moments can be utilised and how to calculate the magnitude of turning forces and moments.. If an object is fixed in place using a pivot (a shaft or other fixing that is designed to allow. Multiple choice questions are perhaps the easiest to complete - you simply put a cross in a box.

A couple consists of a pair of forces that are: Equal in magnitude. Opposite in direction. Perpendicular to the distance between them. Diagram of a couple. Couples produce a resultant force of zero, so, due to Newton's Second law ( F = ma ), the object does not accelerate. The size of this turning effect is given by its torque Which pair of forces act as a couple on the circular object? ANSWER: A. In diagram A, the forces are: Equal in size. In opposite directions. Perpendicular to the distance between them. B is incorrect as the forces are in the same direction. C is incorrect as the forces are different in size. D is incorrect as the distance between the forces is.

Moments. Forces that act on objects that have a fixed point - such as the hinge of a door, or the axle of a wheel - may make that object rotate. We call the turning effect of a force the moment . The fixed point is often called the pivot or fulcrum. How strong the turning effect is depends on: the size of the force. its distance from the pivot http://goo.gl/OHcXh Click Here For Full Exam Question, Answer and Explanation Video. This is the Answer Video for the GCSE Physics Exam Question on Turning F.. The two forces acting in opposite directions on the two sides of the coil form a couple and produces a turning effect on the coil. The forces are produced when the magnetic field due to the current in the coil combines with the external magnetic field to produce two resultant catapult fields around the coil as shown in Figure

(b) Rotational motion : Rigid body should rotate about axis (or pivot). Question 3. (a) What do you understand by the term moment of force (b) State two factors which determine the moment of force. Answer 3: (a) Moment of force : The turning effect of force acting on a body about an axis. Moment of force is also called Torque which comes from the latin word meaning ﬁTo twistﬂ. It is denoted by a Greek letter ‚τ™ (Tau) Factors affecting the moment of force or turning effect The turning effect is greater if: 1. the force applied is away from the axis of rotation Terminal Velocity. When an object falls it accelerates due to its weight (the downward force of gravity acting on the objects mass). As it accelerates its velocity increases. The increase in velocity is accompanied by an increase in air resistance (drag). Eventually the air resistance acting upwards on the objects equals the weight acting.

Circle the correct letter. Answer all questions. 1. Identify the vector from the list below. a. Speed b. Weight c. Time d. Power 2. A recovery lorry tows a broken-down bus. The force of the tow rope on the bus is 400 kN The turning force, M due to the beam around the pivot is: M = weight of the beam x distance from pivot to the Centre of Gravity. M = 100N x 1m = 100 Nm trying to turn the beam clockwise. For balance, the 20N weight must produce a 100Nm turning force in the opposite direction. So the anticlockwise moment due to the 20N weight is Distance = 400m + 300m = 700m. Displacement: Displacement is the distance travelled in a particular direction from a specified point (red line). It can be measured using a ruler if the map is to scale. In this case it can be calculated using Pythagoras's theorem for a right angled triangle. displacement 2 = opposite 2 + adjacent 2

When analyzing forces in a structure or machine, it is conventional to classify forces as external forces; constraint forces or internal forces. External forces arise from interaction between the system of interest and its surroundings. Examples of external forces include gravitational forces; lift or drag.

A number of forces acting at a point may be replaced by a single force which has the same effect on the motion as the original forces all acting together. This single force is called the resultant force. given by : Determining the resultant of opposite or parallel forces acting in a straight line. A resultant force acting on an object may cause. As mentioned in a previous lesson, the resultant force is the overall force acting on an object. This is where all the forces can be__ replaced by a single force__ that has the exact same effect as all the original forces acting together. We need to discuss what happens if all of the forces are balanced, which means the resultant force is 0N I HAVE ALSO ATTACHED THE TEST QUESTIONS AND ANSWERS. Please study it thoroughly.
