The diagram shows two stacks of books of that has a mass of 3 kg and 6 kg. How do their weights compare?

The 6 kg stack has twice the weight of the 3 kg stack.

The 6 kg stack has 1/2 the weight of the 3 kg stack.

The 6 kg stack has 1/3 the weight than the 3 kg stack.

Ball bearings decrease friction in rotating motion because:

they replace sliding friction with rolling friction.

they can be made in all sizes to fit different machines.

they separate surfaces with a cushion of air.

If the net force on a moving object is zero:

the object will not change direction or speed.

the object will slow down and stop.

the object will change direction.

Which of the following would increase the sliding friction between your foot and the floor?

Increasing the weight on your foot.

Separating your foot and the floor.

Putting water between your foot and the floor.

Decreasing the weight on your foot.

Compared to your weight and mass on Earth, if you were on the moon:

your weight would be less but your mass would remain the same.

your weight would increase, but your mass would remain the same.

your weight would remain the same, but your mass would be less.

your weight and mass would be less.

A student attempts to slide a block down a smooth, dry ramp as shown, but the block does not move. The most likely explanation is that:

there are no forces between the block and ramp.

the ramp is not steep enough for gravity to have any effect.

the sliding friction between the block and the ramp is lower than the force of gravity pulling the box down the ramp.

the static friction between the block and the ramp is greater than the force of gravity pulling the box down the ramp.
