The questions in this quiz are suitable for GCSE physics students studying change of shape, Hooke's law, energy stored in a spring and how forces affect the extension of a spring. If you struggled ...

The mass is just sitting there motionless. There is no acceleration and it is in equilibrium. What does this mean? This means that the net force in the y-direction (vertical direction) must be zero. I ...

To investigate experimentally the extension of a spring and how it is related to the applied force, and recall that the extension of a spring is directly proportional to the force applied, provided ...

Why is pancake syrup an example of a resistive force? Some forces are called contact forces because they require objects to touch. One is tension force, found in stretched wires. Another is the force ...

One of the major challenges in the study of vibrations is drawing free body diagrams (FBDs) that are valid for all subsequent motion of the system. Spring forces must be drawn in directions that ...

On 17 March, astronomer John Kovac of the Harvard-Smithsonian Center for Astrophysics presented long-awaited evidence of gravitational waves — ripples in the fabric of space — that originated from the ...

Researchers have a new explanation for why those endless days of childhood seemed to last so much longer than they do now -- physics. According to the theory, the apparent temporal discrepancy can be ...
