480968
Terms in this set (22) Acceleration is increasing or decreasing speed or changing direction, whereas velocity is how much distance you cover in a given amount of time. What is the difference between constant velocity, instantaneous velocity and average velocity? Give an example of an object with constant acceleration.

Speed is the rate of change of distance(basically how much distance(m) has been covered in a particular time(s)). Velocity is the rate of change of displacement( change of distance in a particular direction with respect to time) , and acceleration is the rate of change of velocity per unit of time.

Rate of change of velocity of an object is known as acceleration of that object. If acceleration is constant then it means velocity is changing ( increasing ) uniformly in equal interval of time. Thus by simple reason, velocity keeps increasing uniformly when acceleration is constant.

The equation is F = ma, where F stands for force, m is mass, and a is the acceleration. Because of the link between velocity and acceleration, you can also write this as force = mass × the rate of change of velocity. However, acceleration is the key characteristic here, not velocity.

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.

Velocity describes how position changes; acceleration describes how velocity changes. Two layers of change!

Acceleration. ... Acceleration is the change in velocity per second and is measured in m/s 2. The relationship between acceleration, velocity change and the time taken for the change is given by this formula. acceleration = change in velocity time taken = v - u t. v = final velocity and u = starting velocity.

Acceleration. Acceleration is how fast velocity changes: Speeding up. Slowing down (also called deceleration) Changing direction.

Section 6.2 - Instantaneous Velocity and Acceleration. When an object s distance changes with time, its velocity is the rate at which the distance is changing with respect to time, while its acceleration is the rate at which the velocity is changing with respect to time.

Acceleration is a vector in the same direction as the change in velocity, Δv. Since velocity is a vector, it can change either in magnitude or in direction. Acceleration is therefore a change in either speed or direction, or both. ... When an object slows down, its acceleration is opposite to the direction of its motion.

The velocity of an object is found by taking the derivative of the position function: . Velocity can be thought of as the object's speed and direction, or change in position over time. The acceleration of an object is equal to the derivative of its velocity and describes the object's change in velocity over time.

acceleration is defined as the rate of change of velocity, or, equivalently, as the second derivative of position. ... derivative is a measurement of how a function changes when the values of its inputs change. ..... velocity is defined as the rate of change of position.

The acceleration of a particle is directly proportional to the time t. at t=0, the velocity of the particle is v=16 in/s. knowing the v = 15 in/s and that x = 20 in. when t = 1 s, determine the velocity, the position, and the total distance travled when t= 7 s.

Average speed is distance divided by time. Velocity is speed in a given direction. Acceleration is change in velocity divided by time. Movement can be shown in distance-time and velocity-time graphs.

The equation –v=v0+v2 reflects the fact that when acceleration is constant, –v is just the simple average of the initial and final velocities. Figure 3.18 illustrates this concept graphically. In part (a) of the figure, acceleration is constant, with velocity increasing at a constant rate.

Average speed is distance divided by time. Velocity is speed in a given direction. Acceleration is change in velocity divided by time.

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.
