A lil' help? I'm really bad at science. I don't understand much of this.
1. Define the term “buoyancy force”, use this to explain how ship’s float on water.
2. Explain what friction is and describe everyday situations where friction acts. Give both beneficial and negative uses.
3. Describe all ways that friction can overcome and be reduced.
4. Clearly explain the difference between terms, mass and weight. State the units each.
5. Describe Sir Isaac Newton’s discoveries that relate to forces. How did his discoveries change scientific thinking?
Thankyou.
