1. How does mass and acceleration affect force? (What happens to force if mass increases? What happens to force if acceleration increases? )

Question

2. What is the equation for Newton’s 2nd Law of motion?

3. How do you calculate mass using Newton’s 2nd Law? (rearrange equation of second law to solve for mass)

4. Is slowing down a car an example of acceleration? Explain.

5. Provide an example of how Newton’s Second Law affects your daily life.

Answer 1

force F = rate of change of momentum (change in P/time)
where momentum P = mass m times velocity v
if the mass is constant then
F = m * rate of change of velocity
but
rate of change of velocity is acceleration a
so
Force = mass * acceleration
or F = m a
======================
FIRST law is momentum P which is m v is Constant iff there is no exxternal force on the system.
SECOND law is the one we just did, Force = rate of change of momentum = m a
if mass is constant
THIRD law is for every force there is an equal and opposite force back. If you push on it, you feel it pushing you.

Answer 2

F = m a
so m = F/a
or a = F/m
so what else is new?

Answer 3

If you hit the brakes on your car, its speed changes
as we discussed acceleration is rate of change of velocity
so
if the velocity changes, there is acceleration.

Answer 4

Well the second law (braking force = mass * acceleration) just stopped your car from hitting the bus in the question above.

Answer 5

Good grief - read the chapter in your text please !!!

Answer 6

I agree with Damon if you read your text you should know this
