In the opposite direction.
Which object would have a bigger change of velocity in a collision, a brick or a lego?
The lego.
If the pod was lighter than it was on the previous missions, what would have happened?
The thrusters would have exerted too much force, causing the pod to drift off into space.
What is the definition of mass?
The amount of matter that makes up an object.
What affects the way an object changes in velocity after a collision?
The mass of the object.
Which object would have a bigger change of velocity in a collision, a small car or a big truck?
The small car.
When the pod and the space station collided, why did the pod experience a greater change in velocity?
Because it has less mass.
What is the definition of direction?
The course that something or someone moves in.
When an object is sliding across a surface, why does the object slow down?
Friction
Which object would have a bigger change of velocity in a collision, a wrecking ball or a bowling ball?
The bowling ball.
How much did the pod weigh?
1,100 kg.
What is the definition of the same?
Identical or Not different.
Does a smooth surface or a rough surface have more friction?
The rough surface has more friction.
Which object would have a bigger change of velocity in a collision, a baseball or a ping-pong ball?
A ping-pong ball.
How much less kg did the pod weigh compared to the space station? (415,400-1,100)
414,300 kg
What is the definition of strength?
What you use to describe something physically strong.
Would a bowling ball or a golf ball be harder to lift and why?
The bowling ball would be harder to lift because it has more mass.
Which object would have a bigger change of velocity in a collision, a lemon or a watermelon?
The lemon.
