The relationship between mass and weight?

mass is how much matter, weight includes gravity's pull

Does one human body have a gravitational pull on another body?

Yes, but so slight we can't feel it.

Which is the best description for Inertia?

An object's resistance to a change in motion

Why do astronauts feel 'weightless' in space?

Because they're falling at the rate of gravity,

No. Only planets and moons have gravity.
Yes, but we're stronger than that pull.
It depends on if the other body is good looking or not.

Which is the best description for Inertia?
An object will accelerate according to gravity
An object's resistance to a change in motion
An object will accelerate in the direction of an external net force
An object's resistance to gravity
4
The escape velocity for the Earth is...
9.81 m/s2
1100 mph
11 m/s2
11 km/s
5
Which is the best description for Inertia?
All of these
An object's resistance to a change in motion
An object at rest will tend to stay at rest
An object in motion will tend to stay in motion.
6
Why do astronauts feel 'weightless' in space?
Because there is no gravity in space
Because they're falling at the rate of gravity,
7
Why do we weigh less on the Moon than on Earth?
The Moon's gravity is less
We actually weigh the same, only the acceleration is less.
Because the laws of physics is different there than on Earth.
Because there is no atmosphere on the Moon to push us down.

Why would a bird die on a spaceship without gravity?
Lungs collapse
Can't swallow
Can't poop
Heart would explode
