- Derivation Of Centripetal Force
In mechanics, acceleration is the rate of change of the velocity of an object with respect to time. Acceleration is one of several components of kinematics, the study of motion. Accelerations are vector quantities (in that they have magnitude and direction).
Mathematically, a negative acceleration means you will subtract from the current value of the velocity, and a positive acceleration means you will add to the current value of the velocity. Subtracting from the value of the velocity could increase the speed of an object if the velocity was already negative to begin with since it would cause the ...
- an alternative way of thinking about it would be if velocity equals rate x direction, if you change any variable in that it would change the veloci...
- Quite late, but "flooring it" does refer to suddenly speeding up, and applies especially to cars- It stems from the fact that (at least in older ca...
- Good, clear question. Maybe this helps... F=ma right? so if they are equal, they are in the same direction. Kinda makes sense I guess: if you push...
- Probably no. And the force that drag us backward IS inertia. (Sorry if I'm mistaken. You seemed to treat inertia and 'the force that drag us backwa...
- It all depends on what directions you assign to positive direction of your axis, if it is in the positive direction then is it positive.
- Speed is the magnitude of velocity. Velocity is a vector, which means it has two parts: first, your velocity has a magnitude, which just answers th...
- Your current velocity is 34 m/s in the opposite direction of what is considered the "positive" direction, so it is -34 m/s. Acceleration, 8 m/s^2,...
- Generally, the right side is indicated as the positive direction whilst the left side as the negative direction.
- Just look at the direction of the CHANGE in velocity. If the change is toward the positive direction, it's positive.

Dec 5, 2021 · Acceleration, denoted by the symbol [math]\displaystyle{ \vec{a} }[/math], is a vector quantity defined as the rate of change of Velocity with respect to time. In calculus terms, it is the time derivative of the velocity vector. Acceleration indicates a change in the velocity vector's magnitude, direction, or both.
Feb 20, 2022 · Acceleration is the rate at which velocity changes. In symbols, average acceleration is a= Δv/Δt. The SI unit for acceleration is m/s². Acceleration is a vector, and thus has a …
