Kinematics does not require constant acceleration. There are different equations for different situations. So some of the equations will be valid even when the acceleration is not constant.

Is the kinematics equations true if acceleration is not uniform?
The answer is "No". If acceleration changes, forces of inertia should be taken to consideration. It requires dynamic equations of motion. However, if acceleration changes are not significant, you may continue using kinematics. To check if kinematic solution is within required precision limits you need to compare the solution of kinematic and dynamic equations and decide if kinematic solution is good enough.
Is the statement 'a body moving with uniform speed along a circular path is subjected to uniform acceleration' true or false justify?
This statement is true. This type of movement is called Uniform Circular Motion. For every circular motion at constant speed, there is a constant radial acceleration (always pointing towards the center of the circle) named centripetal acceleration. This constant acceleration ensures that at every moment during the motion the orientation of the velocity is changed so that the object stays in a circular path.
True or false Many people in many types of jobs not just physicists use kinematics ideas?
true ----apex
What percent of earth's gravity does mars have?
The acceleration of an object under the force of gravity alone is*: a = GM/R^2 a = acceleration G = gravitational constant (G = 6.674E-13 Nm^2/kg^2) M = mass of the object/planet R = distance from the center of the object/planet At the equator, an object dropped near the surface of Earth falls with an acceleration of 9.78 meters per square second. At the equator on Mars, and object dropped at the surface will fall with an acceleration of 3.71 meters per square second. Therefore Mars has about 38% of the Earth's gravity. *This equation is only true for spherically-distributed masses
Is it true that the pH of a solution remains constant with increasing basicity?
No, it is not true.
Is it true that the acceleration of an object is constant?
yes. that is very true
If velocity is constant then what is the true accelleration?
In a theoretical scenario with constant velocity, the true acceleration would typically be zero.
When is instantaneous acceleration and average acceleration the same?
That's true throughout any period of time during which the acceleration is constant.

When can you have no acceleration?
To make acceleration equal zero. The velocity must be constant. For example, if velocity is constant at 10 m/s^2 its acceleration is zero. The same is true if velocity is 0 m/s^2.
Why is the velocity 0 when your speed is constant?
It's not. If you speed is constant (but not zero), then your velocity won't be zero, either.You may be confusing this with the following: If your VELOCITY (not your speed) is constant, then your ACCELERATION is zero. Acceleration refers to how quickly velocity changes, so if velocity doesn't change at all, acceleration is zero.

What is the net force when acceleration is zero?
This is a good question. We can relate force and acceleration using the equation F=ma, where m is mass. If the net force, F is zero, that means that either the mass or the acceleration has to be zero so that the equation is true. All objects have mass, so m can't be zero. That means that a has to equal zero in all cases. It is also important to note that acceleration is how fast an object is speeding up or slowing down. An object may be moving and have zero acceleration, if it's velocity is constant. Hope this helps.
Many people in many types of jobs not just physicists use kinematics ideas?
The correct answer is: True. Kinematics ideas are used in a number of different fields, including bio-mechanics (studying how artificial joints work), forensics ( studying how car crashes occurred), and even car racing (determining ideal engine settings, acceleration and braking rates, etc.).

Is this statement true or false In the equation y equals 3 over X's the constant of variation is X's?
False.
A constant speed has a slope of zero on a graph because no acceleration is taking place?
That would be true, in the case of a graph of speed vs time.
