3. A ship wants to sail to another country. What needs to happen for it to do that?
- Upthrust and gravity need to be balanced.
- There needs to be more upthrust than gravity, or the ship will sink.
- There needs to be unbalanced forces, or the ship won't work properly.
- There needs to be more gravity than upthrust, or the ship won't move properly.
- There shouldn't be any upthrust or gravity.
4. Someone puts a brick in a liquid. They use a Newton Meter to measure things. Upthrust makes the brick (and any other object)...
- Balance with the forces around it.
- Appear to weigh less, but it doesn't really. It's weight stays the same.
- Float up to the surface of the liquid.
- Weigh less. Upthrust changes the weight.
- Create unbalanced forces, so the brick (and any other object) sinks.
