1. How does mass and acceleration affect force? (What happens to force if mass increases? What happens to force if acceleration increases? )
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.
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.
F = m a
so m = F/a
or a = F/m
so what else is new?
Well the second law (braking force = mass * acceleration) just stopped your car from hitting the bus in the question above.
1. According to Newton's Second Law of Motion, force is directly proportional to mass and acceleration. So, if mass increases while acceleration stays constant, the force will also increase. On the other hand, if acceleration increases while mass remains constant, the force will also increase.
2. The equation for Newton's Second Law of Motion is F = m * a, where F represents force, m represents mass, and a represents acceleration.
3. To calculate mass using Newton's Second Law, we need to rearrange the equation. We start with the equation F = m * a and rearrange it to solve for mass. Dividing both sides of the equation by acceleration gives us m = F / a.
4. Yes, slowing down a car is an example of acceleration. Acceleration is a change in velocity, which can refer to both speeding up and slowing down. When a car slows down, it experiences a negative acceleration, also known as deceleration. So, in this case, the car's acceleration is in the direction opposite to its initial motion.
5. An example of how Newton's Second Law affects daily life is when we push or pull an object. The force we apply to the object depends on both its mass and the acceleration we want to achieve. For instance, if we want to move a heavy piece of furniture, we need to apply a greater force because of its larger mass. Conversely, if we want a lightweight object to accelerate quickly, we can apply a smaller force since its mass is smaller.
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.
Good grief - read the chapter in your text please !!!
I agree with Damon if you read your text you should know this
ps. I'm not a teacher
