Explain why it is easier ti drive a nail with a heavier hammer?
Hint: what would happen to impulse when using a heavier hammer?Explain why it is easier ti drive a nail with a heavier hammer?
impulse = force(time)
impulse is the momentum
momentum = (mass)(velocity)
if we increase the mass we have a greater impulse, which means greater force driving the nail.Explain why it is easier ti drive a nail with a heavier hammer?
potential energy is greater with a heavier hammer (mgh) if m, or mass, is larger, then the kinetic energy released on the nail will be greater. mgh = .5mv^2
