Two crates, one heavy and one light, are at rest on a waxed floor. Which crate will need the greater force to give the same change in speed? Explain.

Question

anonymous · Answer

The heavier crate needs greater force.
This is because, with the the heavier crate, you need to overcome a greater frictional force to move the crate from rest.
Ff = μ N
Ff=frictional force
μ=static friction coefficeint
N=for an object pushed horizontally, N is Weight

The greater the weight, the greater the Frictional Force.
