6th grade science review

Question 1

What is potential energy?

Answer 1

It is the amount of energy that is stored in an object. (For example if you are about to go down a slide, and you are on top of the slide, you have kinetic energy.)

Question 2

What is kinetic energy?

Answer 2

It is the amount of energy a moving object has due to its motion. (For example, if you are going down a slide, you have kinetic energy because you are in motion and actively moving.)

Question 3

What is energy transfer?

Answer 3

Energy transfer is the movement of an object from one location to another.

Question 4

What is energy transformation?

Answer 4

Energy transformation is energy changing from one form to another.

Question 5

What is density? What is the formula to calculate density?

Answer 5

Density is how compacted the mattes in an object is. The formula for density is mass over volume.

Question 6

How do you know if an object will float or sink?

Answer 6

Water has a mass of 1g/ml which means that if an object is more than 1g/ml, it will sink, and if an object is less than 1g/ml, it will float.

Question 7

What is volume and its formula? What is meniscus?

Answer 7

Volume is the amount of space an object takes up (The formula is mass/density=volume). Meniscus is the upward or downward curve that marks how filled a substance is.

Question 8

What is mass and what is the formula used to calculate mass?

Answer 8

Mass is the amount of matter in an object (The formula is density times velocity is equal to the mass).
