Acceleration is the rate of change of velocity. At any point on a trajectory, the magnitude of the acceleration is given by the rate of change of velocity in both magnitude and direction at that point. The true acceleration at time t is found in the limit as time interval Δt → 0 of Δv/Δt.

: 150 The physics concept of force makes quantitative the everyday idea of a push or a pull. Forces in Newtonian mechanics are often due to strings and ropes, friction, muscle effort, gravity, and so forth. Like displacement, velocity, and acceleration, force is a vector quantity. Laws First law
So a velocity might be "20 m/s, downward". The speed is 20 m/s, and the direction is "downward". Acceleration is the rate of change of velocity. Usually, acceleration means the speed is changing, but not always. When an object moves in a circular path at a constant speed, it is still accelerating, because the direction of its velocity is changing.
- 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.
May 2, 2024 · acceleration, rate at which velocity changes with time, in terms of both speed and direction. A point or an object moving in a straight line is accelerated if it speeds up or slows down. Motion on a circle is accelerated even if the speed is constant, because the direction is continually changing. For all other kinds of motion, both effects ...

Dec 5, 2021 · Acceleration, denoted by the symbol a →, 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. Acceleration is an instantaneous value, so it may change over ...
