Contact Forces
What is an example of a contact force?
What is Any example that includes touching an object that is having a force acted on it!
What is an example of a non-contact force?
What is Anything example that pushes or pulls without touching!
What is an example of gravity?
What is Any example that explains that gravity pulls us down and pulls objects towards the core.
How often you should be checking focus
What is everyday?
What is the contact forces that is 'away from you'?
What is Push!
What are the 3 non-contact forces we learned about?
What is Magnetism, gravity, and electricity!
Does the pull of gravity change between Earth and Space?
What is Yes!
This is because the pull of gravity isn't as strong in space as it is on Earth. This is why we can float around in space and would feel alot lighter!
What are pencils?
What is the contact forces that is 'towards you'?
What is Pull!
What is the definition of a non-contact force?
What is A force that doesn't touch the object it is acting on!
Does Earth or Mars have more gravitational pull?
What is Earth?
What is 9 weeks?
What is the definition of a contact force?
What is A push or pull force that touches the object it is acting on.
What non-contact force keeps us on the ground and stops us from floating around?
What is Gravity!
If an object weighs more, is the attraction/pull of gravity stronger? (Hint: Think of dropping a marble and a feather from the same height at the same time, do they land at the same time.)
Yes, mass/weight does impact the strength of the attraction of gravity.
Do you create a new substance in a chemical change?
What is yes?
Is a static balloon pulling your hair towards it a contact force?
What is No.
It may look like it, but the balloon is pulling your hair without actually touching it, this is because the balloon attracts the opposite charges in your hair invisibly. Static electricity is a non-contact force!
What non-contact force causes a 'zap' when you touch another person after shuffling on the ground? Bonus: Explain why this happens!
What is Static electricity!
This happens because as we shuffle on the ground we are collecting extra charges. Once we touch someone else the extra charges want to escape from our body and are attracted to the opposite charges of another person or object, so that jump!
Does the moon have a stronger or weaker gravitational force/pull than the Earth?
The moon has a weaker gravitational force than the Earth. These means we weight a lot less on the moon compared to the Earth.
3 types of rocks that exist on earth.
What is igneous, metamorphic, and sedimentary?
