Which statement correctly describes static friction?
it prevents surfaces at rest from sliding past each other
it opposes motion of objects that are already moving
it is the resistance of an object to particles in a fluid
it only opposes the force of gravity
The tendency of an object to resist a change in motion is called ________________.
inertia
force
friction
drag force
When will an object sink?
it's less dense than the fluid
it's more dense than the fluid
it has the same density as the fluid it's in
it is filled with a gas
Both boats are made of metal. Why does the one on the right sink?
it is filled with water instead of air
the one on the left is made of steel instead of iron
it forces less water away than the one on the left
it is blue instead of gray
What is potential energy?
moving energy
stored energy
renewable energy
non renewable energy
How is kinetic energy different from potential energy?
it depends on mass and speed instead of mass and position
it depends on mass and position instead of mass and speed
kinetic energy is stored energy, but potential energy is the energy of motion
kinetic energy is a form of thermal energy, but potential energy is a form of radiant energy
When energy changes from one form to another, we call it a _______________.
transformation
creation
expiration
compilation
