I have to write a paper for Physics and I'm completely stuck!!!

Velocity is a measure of how fast something is travelling, and in what direction. It's given in units of m/s and the direction (which makes it a vector)
Acceleration is a measure of how quickly somethings velocity is changing. It's given in units of m/s² and the direction (which makes it a vector also)
Force is a measure of the amount of 'push' or 'pull' (for lack of better words) that is applied to a mass to make it accelerate. It's given in units of called 'Newtons' and one Newton equals the force required to accelerate one killogram by one meter/second every second. (At the end of 2 seconds, the mass will be traveling at 2 m/s, at the end of 3 seconds, 3m/s, etc.) Force also has a direction component so it, too, is a vector.
Hope that helps.

Velocity is a vector representing the speed and direction of an object. Velocity does not = speed. Speed is a component of velocity though.
Usually measured in m/s
Acceleration is a measure of change in velocity with respect to time.
Measuered in m/(s^2)
Force is what causes an object to accelerate. Acceleration is proportional to force. If the net force is 0, then there is no acceleration. Force is measured in Newtons = kg(m*s^2)
That's about all I remember from physics class.

speed is the fee (speed) at which a physique travels in a single course. occasion: ninety m/s northwest Acceleration is the fee at which some thing will advance its speed, as an occasion: 10 m/s^2 (10 meters consistent with 2d squared), meaning that each and each 2d, the article will advance its speed by using 10 meters consistent with 2d. A connection between acceleration and rigidity may well be modern-day in Newton's 2d regulation, which states: f = ma, the place: f is rigidity m is mass a is acceleration So the rigidity is comparable to the acceleration circumstances the mass of an merchandise. and don't subject approximately having a complicated time in physics. I used to warfare (for a nerd... that's low A's) in it until I grew to grow to be a physics nerd. purely placed me on your contacts, then i'm going to consistently see your phys questions and with any luck be waiting to respond to them ;)

Force needs to be applied to an object to accelerate it, and acceleration will bring it to a final velocity, after the force stops being applied.

Acceleration - The rate of increase in velocity when starting from rest.
Velocity - The speed travelled in a given direction.
Force - The amount of energy that can be applied to an object.
I think these might be vague...but hope they work for you...good luck!!

Velocity is a constant speed in one direction.
Acceleration is a change in either speed or direction or both.
Force is applied to an object to accelerate it.

velocity is pretty much the rate of speed or speed of motion.
acceleration is the rate of change of velocity.
force is what causes an object to move, and which causes velocity and acceleration

I just did this in school, go to a website called hotmath.com and use this password,xe16359de, and go to science.

I was going to say Physics 101 ..but. ??
