The Law of Conservation of Energy states:
Energy can created or destroyed but not transformed
Energy cannot be created or destroyed, it can only transformed
Energy can't be created, destroyed or transformed
Energy cannot be created or destroyed.

All of the above
What force causes a roller coaster cart to slow down the most?
friction
weight
gravity
air resistance
What is the formula for Kinetic Energy?
KE = mass x velocity
KE= 1/2 x mass x velocity 2
KE = mass x gravity x height
KE = mass x velocity / 2

Respiration is a vital function that all living things carry out.
True
False
For respiration to take place glucose needs to react with substance A. Select substance A.
Carbon dioxide
Water
Oxygen
Ozone
During exercise our body needs to produce more energy by respiration thus it needs
less oxygen
more oxygen
Chloroplast
The correct word equation for aerobic respiration is
carbon dioxide + water (+ energy) → glucose + oxygen
water + oxygen → carbon dioxide + glucose (+ energy)
glucose + oxygen → carbon dioxide + water (+ energy)
glucose + water → carbon dioxide + water (+ energy)
