Why does the paper clip float?

The magnetic force is stronger than gravity at that moment.

Paperclips normally floats, so nothing strange is happening here.

Metals and magnets do not attract each other.

How do light rays travel?

They curve around objects that are in their way.

Your eyes are light sources and that's why we can see.

They go through all objects and never absorbed.

Why might a ball starting at position 4 of this ramp be rolling faster when it gets to the runway than a ball that starts at position 2 of the ramp?

There is more time for gravity to act on the ball from the higher position

Gravity is a stronger force at a higher position

It takes the ball longer to roll down the ramp

It won't be rolling faster, the ball will go faster if it starts at position 2

The ball starts at the top of the ramp, rolls down, and hits the flag pole at 200 units of force. The flag pole doesn't fall. How much force does the flag pole push back on the ball?

Equal amount (exactly 200 units)

Study the picture and choose the correct statement.

Drop the hammer from the highest position and it will have the most time to gain energy to drive the post into the ground faster.

Drop the hammer close to the post is best to get the post into the ground faster.

Lower the mass of the hammer will increase its energy to drive the post into the ground faster.
