A key is lying motionless on a carpet floor. The key is......

• Contemplating its life choices on why it is a key

• At rest

• Moving at a constant speed

• A key lying on the carpet floor

Answer explanation

You technically wouldn't be wrong saying the key is a key lying on a carpet floor. That is literally what it is, but speaking in graphing motion, the key would be at rest.

(The key on this image is not on a carpet floor it is on a white background.)

You throw a desk 4 meters away from where you are standing. The desk lies unmoving for 2 seconds. But then you're angered enough to walk over to where you threw the desk and threw it again 4 meters back to where you were standing originally.
