Question 1.
What will happen to the stone if the thread is released?
Show hintHide hint
Think about how centripetal force works when it is no longer acting.
Question 2.
What is a tangent in relation to a circle?
Show hintHide hint
Remember what we discussed about tangents during our session.
3Question 3.
What happens to an object when the centripetal force is removed?
- It stays in circular motion
- It moves in a straight line
- It falls down
Show hintHide hint
Remember how centripetal force functions.
4Question 4.
True or False: The same gravitational force that pulls an apple to the ground keeps the moon in orbit.
- True
- False
Show hintHide hint
Link the apple's fall with the moon's orbit.
Question 5.
If two planets with masses of 6 x 10^24 kg and 3 x 10^24 kg are separated by a distance of 1.5 x 10^11 m, what is the gravitational force between them?
Show hintHide hint
Remember to square the distance in the denominator.
Question 6.
How would the gravitational attraction between two objects change if the distance between them is halved?
Show hintHide hint
Consider how changing distance changes attraction intensity.
