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).

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.

Acceleration is a measure of how fast velocity changes. Acceleration is the change of velocity divided by the change of time. Acceleration is a vector, and therefore includes both a size and a direction. Acceleration is also a change in speed and direction, there is: Speed (a scalar quantity) (uses no direction) Distance is how far you traveled
Acceleration is the name we give to any process where the velocity changes. Since velocity is a speed and a direction, there are only two ways for you to accelerate: change your speed or change your direction—or change both.
- Can't something change direction and not be accelerating??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...
- Can someone please give the correct answers for the car exercise? I don't understand the explanation...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...
- Could someone re-explain the picture with the four cars? I'm not quite sure about why the car slows ...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...
- So when we accelerate, we feel as if a force was dragging us backwards and let us feel the inertia. ...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...
- If i'm traveling east at 20 mph in my toyota camry and got bored with the traffic and changed lanes ...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.
- What is the main or basic difference between speed and velocity? Acceleration is used only for chang...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...
- I don't understand: How does -34m/s+8m/s^2(3s)= -10m/s?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,...
- how do we know which is positive or negative direction when the origin point is not given ?Generally, the right side is indicated as the positive direction whilst the left side as the negative direction.
- how do u determine if the acceleration is positive or negative?Just look at the direction of the CHANGE in velocity. If the change is toward the positive direction, it's positive.
