1.Explain frame of reference. How is it different when you are riding inside a car or standing by the highway? 2. Explain Newton’s three laws of motion.

3. When riding in a car that suddenly stops, how is it different when you are wearing a seatbelt or not? Explain how Newton’s laws apply.

4. Define force.

5. Explain balanced and unbalanced force.

6. Describe the four fundamental forces? Arrange them from weakest to strongest.

7. What is work and power and their relationship?

See explanation

Explanation:

A frame of reference simply refers to a set of coordinates which is used to determine the position and velocity of objects all the objects found in that particular frame. The person inside the car and standing by the highway are in different frames of reference.

Newtons first law of motion states that an object will continue to be at rest or in a state of uniform velocity until it is acted upon by an external force.

Newtons second law states that rate of change of momentum is directly proportional to the impressed force.

Newtons third law states that action and reaction are equal and opposite.

The action of applying brakes leads to an equal reaction of a sudden forward movement. Seat belts help to prevent the occupants of a car from being injured by the sudden stoppage of the car.

Force is simply defined as a push or pull.

Balanced forces do not lead to acceleration of a body but an unbalanced for leads to acceleration of a body.

strong nuclear force, electromagnetic force, weak nuclear force and gravity

Power is the rate of doing work while week is said to be done when the force applied moves a distance in the direction of the force. Power is defined as work/time.

i wanna say it’s between b and d, leaning more towards b.

laticia draws the diagram below to show earth’s magnetic field.

answer

the arrows to the right of earth should point up.
