Both speed and acceleration can be variable, depending on the circumstances.

What is the difference between uniform and variable velocity?

Uniform velocity is constant speed in a straight line, while variable velocity changes in speed or direction over time. Uniform velocity has no acceleration, whereas variable velocity may have acceleration due to changes in speed or direction.


What is speed does not change over time called?

A change in speed is a change in velocity - so, a change in speed is an example of acceleration! Acceleration may be positive or negative. Negative acceleration is sometimes called deceleration. When a force acts on an object; it may change the object's acceleration (speed, direction, or both).


What is the difference between constant velocity and variable velocity?

Constant velocity has speed always constant along the direction with respect to time. Variable velocity changes its speed with respect to time. Constant velocity has zero acceleration. Variable velocity has non-zero acceleration . An object moving at a constant velocity maintains both the same speed and direction. An object moving at a variable velocity can be changing speed or direction of travel or both.


How does a change in speed affect acceleration?

Acceleration is directly proportional to the change in speed. If the speed increases, acceleration is positive. If the speed decreases, acceleration is negative. The magnitude of acceleration is determined by the rate at which the speed changes.


How do you calculate speed when you have the force mass and acceleration?

You can calculate speed by dividing the force by the mass to get acceleration, and then multiplying the acceleration by time. Speed = acceleration x time.

In physics what is variable acceleration and please give at least two examples of it?

Variable acceleration refers to an object's velocity changing by different amounts over time. This means that the object's speed is not changing at a constant rate. An example of variable acceleration is a car speeding up as it merges onto a highway, where the acceleration is increasing. Another example is a rocket slowing down as it enters the atmosphere due to air resistance, where the acceleration is decreasing.


What are dependent and independent variable in algebra?

the dependent variable is the y-value. the dependent variable means it relys on another variable for its answer. without the other variable this variable would not exist. the independent variable is the x-value. the independent variable can exist on its own without the dependent variable. i mention x-values and y-values... this is only if you are using an x and y value for your application. there are other applications... like speed... where the dependent variable for speed would be time and the independent variable for speed would be distance. and for acceleration the dependent variable would be speed and the independent variable would be distance.

The relationship of speed and acceleration?

Acceleration is the time rate of change of speed. Acceleration = speed/time.

Acceleration is directly proportional to the change in speed. If the speed increases, acceleration is positive. If the speed decreases, acceleration is negative. The magnitude of acceleration is determined by the rate at which the speed changes.


What is the definition of variable motion?

Variable motion refers to motion that is not constant, but changes in speed and/or direction over time. This could include acceleration, deceleration, or changes in velocity during an object's movement.


Is acceleration the same as speed?

Acceleration is the rate that speed changes.


How do you calculate speed when you have the force mass and acceleration?

You can calculate speed by dividing the force by the mass to get acceleration, and then multiplying the acceleration by time. Speed = acceleration x time.


For a car moving around a circular track at a constant speed the acceleration is?

constant speed=0 acceleration Acceleration is the change in speed. If the speed doesn't change(ie constant) the acceleration is zero.


What happens to your speed if you have a negative acceleration do you speed up or slow down?

If you have a negative acceleration, you are slowing down. Acceleration is the rate of change of speed, so a negative acceleration means a decrease in speed.
