- 1. a vehicle's capacity to gain speed within a short time: "a Formula One car is superior to an Indy car in its acceleration"
May 2, 2024 · Acceleration is the rate of change of velocity, which includes both speed and direction. Learn how to calculate acceleration, its units, and examples of acceleration in different types of motion.

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).
Acceleration is the rate of change of velocity, which can be caused by changing speed or direction or both. Learn how to calculate acceleration, distinguish it from velocity, and understand its signs and effects with examples and diagrams.
- 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.
Acceleration is defined as. The rate of change of velocity with respect to time. Acceleration is a vector quantity as it has both magnitude and direction. It is also the second derivative of position with respect to time or it is the first derivative of velocity with respect to time.

- What is centripetal acceleration?When an object is moving in a circle and its acceleration vector is pointed towards the centre of that circle, it is known as centripetal accelerat...
- What is gravitational acceleration?Gravitational acceleration is used for indicating the intensity of the gravitational field. It is expressed as m/s2 and its value on the surface of...
- What is tangential acceleration?Tangential acceleration is defined as the rate of change of the tangential velocity of a particle in a circular orbit. There are 3 possible values...
- What is radial acceleration?When there is an acceleration of an object along the radius directed towards the centre, it is known as radial acceleration. It is expressed as rad...
- What is Coriolis acceleration?The acceleration due to the rotation of the earth is known as the Coriolis acceleration. This acceleration is experienced by the particles that mov...
