Lesson: Tension Forces High School Physics

Physics

In this lesson, we will learn how to determine the tension forces acting on flexible objects that connect the members of systems of rigid objects.

Worksheet: 20 Questions

Q1:

Two identical objects are connected to each other by a rope as shown in the diagram. A second rope is connected to one of the objects. The masses of the ropes are negligible. A short time after constant force F is applied to the end of the second rope, both objects uniformly accelerate in the direction of F across a smooth surface. Tension T is produced in the rope that the force is applied to, and tension T is produced in the rope that connects the objects. Which of the following statements correctly represents the relationship between T and T?

Q2:

An object with a mass of 25 kg is at rest, suspended vertically from a platform by two ropes, as shown in the diagram. The masses of the ropes are negligible. What is the angle between the two ropes at the point that they connect to the object?

Q3:

Two objects of mass 13 kg each are connected to each other by a rope, as shown in the diagram. A second rope is connected to one of the objects. The angle between a line parallel to the surface the objects are placed on and the direction of the second rope is 28. The masses of the ropes are negligible. A short time after a constant force F is applied to the end of the second rope, both objects accelerate horizontally across a smooth surface. A short time after the force is applied, a tension ||=14TN is produced in the rope that the force is applied to and a tension ||T is produced in the rope that connects the objects.

Find the acceleration of the objects.

Find ||T.
