• There are two methods to draw force vector diagrams: o The Tip-to-Tail Method, where you align the vectors tip to tail and construct the resultant force by joining the free ends. o The parallelogram method. Where you place the vectors tail to tail, construct a parallelogram and measure the diagonal which represents the resultant force. Question
A resultant force is a single force that describes all of the forces operating on a body. When multiple forces act on one object, the forces can be combined to produce one net force that describes the combined action of all of the forces. This single resultant force determines:
A book is resting on a table. A student draws a correct free-body force diagram for the book as shown below.
Topic Specification. Resultant Force Revision. Multiple forces can act on an object at one time, and we can use the idea of a resultant force to determine the direction of motion of the object. The resultant force can be calculated and shown in vector diagrams. What is resultant force?
Q1. A bike is accelerating on a flat, straight road. How would the free-body diagram represent this? Q2. What two things does a free-body diagram tell us about the forces acting on a body? . Q3. A child is learning to ride a bike while her mum runs alongside, pushing and keeping her upright. How would you calculate the resultant force on the bike?
A resultant force is a single force that describes all of the forces operating on a body. When many forces are applied to an object they can be combined (added) to produce one final force which describes the combined action of all of the forces. This single resultant force determines:
We know that a push or a pull has both magnitude and direction (therefore, it is a vector quantity), so we can define force as the push or pull on an object with a specific magnitude and direction. Force can be represented by vectors or expressed as a multiple of a standard force.
