Answer:
Newton’s first law (i.e about inertia) is best shown in this example.
Explanation:
- Newton's first law states that every object continues in its state either motion or rest until it is acted upon by any other external force.
- As the student is in motion when he/ she hits the patch of ice. as no external force is applied, he/she continues the motion by sliding over the ice due to inertia.
- Until the friction and other resistance force balances the motion he/she will not stop sliding.
1.Proteins. Proteins are found in the blood plasma and all over the body. The functions of protein include: repair and maintenance of body tissue, they are components of some hormones e.g. insulin, they make up enzymes, they make up transport molecules such as hemoglobin.
Lipids. These are used for energy storage and production. They provide energy for muscle and body processes.
Starch. Starch is converted into glucose for energy in the body.
Sugar . Sugar in the form of glucose is used by every cell in the body for energy.
Calcium. A mineral that is used by the body for building and keeping bones and teeth strong.
