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 ). [1] [2] The orientation of an object's acceleration is given by the orientation of the ...
Learn how to calculate and measure acceleration, the rate of change in speed or velocity of an object. Find out the difference between constant speed, constant acceleration and deceleration, and see examples and equations.
Learn what acceleration means, how to calculate it, and how to distinguish it from velocity. See how acceleration can be positive or negative, and how it affects speed and direction.
- 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.

- 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...
- 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...
- 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...

Jan 2, 2023 · Learn what acceleration is, how to calculate it, and what types of acceleration exist. See graphs, problems, and solutions related to acceleration in physics.
Since acceleration is a velocity change over a time, the units on acceleration are velocity units divided by time units - thus (m/s)/s or (mi/hr)/s. The (m/s)/s unit can be mathematically simplified to m/s 2. The Direction of the Acceleration Vector. Since acceleration is a vector quantity, it has a direction associated with it. The direction ...
