Forces And Elasticity (GCSE Physics)

A metal spring of k = 800 N/m is compressed by 0.05 m. What is the elastic potential energy stored?

When gear A turns clockwise and meshes directly with gear B, what is the direction of rotation of gear B?

The gradient of a force versus extension graph for a spring gives:

What is the expression for the moment (torque) M produced by a force F acting at a perpendicular distance d from a pivot?

Which equation defines pressure p applied uniformly over area A by a force F?

A block attached to a spring is stretched and the work done (area under force–extension) is 2.0 J. If the spring constant is 100 N/m, what was the extension x? (Use 1/2 k x^2 = 2.0)

A spring stores 4.0 J of elastic potential energy when stretched by 0.080 m. What is the spring constant k (N/m)?

A material has Young’s modulus E defined as stress / strain. If a wire of original length 1.0 m extends by 1.0 mm under a given load, what is the strain?

Which expression gives the spring constant k for a spring stretched by a force F producing an extension x?

What is meant by the elastic limit of a material?

Plastic deformation of a material means:
