... Measuring acceleration is a more difficult way of measuring mass than using a spring or a balance. The balance exploits the fact that gravity acts proportional to mass, so that at a given place all masses accelerate equally. ...

Tension
... • The magnitude of the force exerted by a spring is proportional to the amount it is stretched. • F = kx – F: force exerted by the spring (N) – k: force constant of the spring (N/m or N/cm) – x: displacement from equilibrium (unstretched and uncompressed) position (m or cm) ...

Section 7.3 Torque
... Most of the mass of a hammer is in its head, so the hammer’s moment of inertia is large when calculated about an axis passing through the end of the handle (far from the head), but small when calculated about an axis passing through the head itself. You can feel this difference by attempting to wave ...

4.1 Resistance in Mechanical Systems
... (a) At first, F < Fstatic,max and the crate does not move. Notice that Fstatic,max = μsN. As you increase F, the force of friction Fstatic increases to exactly match F so that Fstatic = F. (b) At the instant F becomes greater than Fstatic,max, a net force exists on the crate and it accelerates to th ...
