How can you find the work done on an object from a force vs displacement graph?
From a force-displacement graph we can:
- Read forces directly from the graph.
- Read displacements directly from the graph.
- Use the area under the graph to find the work done by the force. This is equal to the kinetic or potential energy the object gains due to the application of the force.
How do you find the distance on a distance time graph?
Distance-time graphs
- If an object moves along a straight line, the distance travelled can be represented by a distance-time graph.
- Calculate the speed of the object represented by the green line in the graph, from 0 to 4 s.
- change in distance = (8 – 0) = 8 m.
- change in time = (4 – 0) = 4 s.
How do you determine velocity from force and distance?
Equating work and kinetic energy allows you to determine velocity from force and distance. You cannot use force and distance alone, however; since kinetic energy relies on mass, you must determine the mass of the moving object as well.
How do you calculate the distance traveled in physics?
If you know how fast and how long something was traveling, you can solve for the distance traveled. You just need to rearrange the velocity formula above to get the distance formula in physics: {bigtriangleup x} = (velocity) (time) △x = (velocity)(time) A plane travels 150 miles per hour on it’s way from Atlanta to San Diego.
How do you find the initial velocity of a graph?
A = Length * Height – The rectangular part of the velocity area graph, where the width is the time traveled (t) and the height is the initial velocity. A = ½ Base * Height – The triangular part of the velocity area graph, where the base is the the time traveled (t) and the height is the change in velocity.
How do you find the distance covered by a moving object?
Find out the velocity of the moving object in a given direction. It is normally expressed as meters per second (m/s). Say the velocity is 10 m/s, north. Calculate the time traveled on that velocity. It is normally measured in seconds (s). Say the velocity is maintained for 20 seconds. Multiply velocity by time to get distance covered in meters (m).
