Top Answer

For an object's speed to change (increase or decrease), the object must be accelerating. If there is an acceleration, there is a non-zero net force acting on the object.

note: Velocity and speed are different. An object's velocity can change without the speed changing. Example of this is centripetal acceleration. The object's velocity changes directions, thus the velocity changes. The magnitude (or speed), however, stays the same (if only a radial acceleration is present).

0Gforces An acceleration

Acceleration is constant.Speed increases linearly with time.Distance increases exponentially with time.

speed=distance/time. Therefore, eg the speed increases, the time taken thus decreases. :D

An object with an increasing speed is in fact accelerating, hence the acceleration vector may be continually changing (but >0) with time.

The graph of distance vs time increases exponentially as speed increases.

It undergoes acceleration, its speed decreases, the magnitude of its velocity decreases, and it takes more time to arrive at its final destination.

It undergoes acceleration, its speed decreases, the magnitude of its velocity decreases, and it takes more time to arrive at its final destination.

The speed of an object at one instant of time is its instantaneous speed.

The speed of an object at any instant in time is its instantaneous speed.

The speed of an object as a certain point in time is its instantaneous speed.

The speed of an object can be found by dividing the distance travelled by the object by the time taken for the object to travel that distance. Speed=Distance/Time

Speed Increases. - Apex(;

Speed of an object at one instant of time is the object's instantaneous speed.(Not velocity.)

Speed increases when a body accelerates under the influence of a force. Newton's second law: acceleration= force/mass. Acceleration is the rate of change of speed over a period of time. For example if you drop an object, it's speed increases by 9.8 meters per second every second.

Instantaneous speed-the speed of an object at any instant time. When you ride in a car, the instantaneous speed is given by the speedometer.

No, but the slope of the graph does.

Acceleration is the change in velocity of an object over time. Take note that velocity is a vector quantity which means that it has magnitude and direction...Thus...An object undergoes acceleration when:1. there is a change in the magnitude of the velocity (speed) of an object.2. there is a change in direction of an object.3. it changes both in direction and magnitude.

The speed of an object at a specific point in time is its instantaneous speed. Also, instantaneous rate of change of displacement.

Its speed is whatever the object is going at the time. Multiply acceleration by time and then add initial velocity.

Time and Speed Time and Speed

Speed = distance / time.

Time in no way has an effect on speed.

The ratio of distance at which an object is moving to time refers to its speed. A high speed means that the object covers a long distance within a short time.

distance covered by the object per unit time is the speed of the object.

The speed of an object at a time is found by determining its rate of change of distance. If the speed is constant, it can be determined by the ratio of distance to time taken.
