If an object, such as a ball of clay sinks, what would we need to do to its volume to make it float?
Clay can't float
Increase the volume
Decrease the volume
Keep the volume the same
The density of fresh water is 1 g/cm3.

sink
float
neutrally buoyant
no way of knowing what would happen

TRUE or FALSE if you push a box across a surface like Ice with no friction, it will NEVER stop
TRUE, as long as it doesn't run into something it will keep going and going and going
FALSE, it will stop very quickly
This car is turning, but there’s a puddle of water in the road. Which diagram best shows how the puddle will affect the path of the car after it hits the puddle?
Which of the following represents and is true about kinetic friction? SELECT ALL THAT APPLY
A box being pushed but not moving
A box being pushed and sliding across the floor
The magnitude of kinetic friction is greater than static friction
The magnitude of kinetic friction is less than static friction
The magnitude of kinetic friction is equal to static friction
How can friction be reduced?
increase the force acting between the 2 surfaces by decreasing the weight of the object on the surface
increase the roughness of the 2 surfaces coming in contact
reduce the surface area between the interacting surfaces
