What can you say about the motion of a body if its velocity- time graph is a straight line?

A velocity-time graph is often a misnomer since it is, in almost all cases, a graph showing the component of velocity in the direction towards and away from a fixed point of reference. The graphs do not usually included any information on the motion in a perpendicular direction. Therefore, a straight line in a "velocity"-time graph indicates that there is no acceleration in the radial direction.

Do balanced forces cause motion?
No. An unbalanced force causes motion, but balanced forces keep a body in motion in a straight line at constant velocity, or at rest at constant 0 velocity.
What can you say about the motion of a body if its displacement time graph is a straight line?
The object is moving at a constant speed.
What will you say about motion of body if distance time graph is straight line having constant angel with time axis?
If the distance/time graph is a straight line that makes a constant angel with the time axis, then the body's speed is constant, and is equal to the slope of the straight line (tangent of the constant angel).
Will a change in velocity happen in direction the force is applied explain?
Yes. When an outside force acts upon a body in motion, it will move in the direction of the force. This is inferred from Newton's first law of motion that states that a body at rest remains at rest or a body in motion remains in motion in a straight line at constant velocity, unless acted upon by an outside force.
How can you obtain the average velocity and instantaneous velocity from a displacement - time graph?
You cannot because a displacement-time graph is concerned only with radial motion: displacement from a fixed point of reference. Any transverse motion is completely ignored. Thus, if you had a body going around in a circle about the point of reference, its speed would be recorded zero!
What can you say about the motion of a body if it's velocity-time graph is a straight line inclined with the time-axis?
uniformly accelerated motion
Do balanced forces cause motion?
No. An unbalanced force causes motion, but balanced forces keep a body in motion in a straight line at constant velocity, or at rest at constant 0 velocity.
Is the displacement time graph of a body moving with uniform velocity always a straight line?
A displacement vs. time graph of a body moving with uniform (constant) velocity will always be a line of which the slope will be the value of velocity. This is true because velocity is the derivative (or slope at any time t) of the displacement graph, and if the slope is always constant, then the displacement will change at a constant rate.
What can you say about the motion of a body if its displacement time graph is a straight line?
The object is moving at a constant speed.
What newton first law of motion?
Newton's first law of motion states that a body at rest remains at rest and a body in motion remains in motion at constant velocity in a straight line unless acted upon by an unbalanced force.
Give an example of a body that is in motion but that is also in equilibrium?
A body with constant velocity in a straight line or direction, dV/dt =0.

What can you say about the motion of a body if its distance-time graph is a straight line?
It is moving at a constant speed with no acceleration nor decceleration
What does Newton's 1st law of motion state?
Newton's first law of motion states that a body at rest remains at rest and a body in motion remains in motion in a straight line at constant velocity unless acted upon by an unbalanced force.

If the distance/time graph is a straight line that makes a constant angel with the time axis, then the body's speed is constant, and is equal to the slope of the straight line (tangent of the constant angel).

Yes. When an outside force acts upon a body in motion, it will move in the direction of the force. This is inferred from Newton's first law of motion that states that a body at rest remains at rest or a body in motion remains in motion in a straight line at constant velocity, unless acted upon by an outside force.
If an object is moving at unifrom acceleration what is its velocity?
A body moving at a uniform speed may have a uniform velocity, or its velocity could be changing. How could that be? Let's look. The difference between speed and velocity is that velocity is speed with a direction vector associated with it. If a car is going from, say, Cheyenne, Wyoming to the Nebraska state line at a steady speed of 70 miles per hour, its velocity is 70 miles per hour east. Simple and easy. Uniform speed equals uniform velocity. (Yes, I-80 isn't perfectly straight there. Let's not split hairs.) But a car moving around a circular track at a uniform speed is constantly changing direction. Its speed is constant, but its velocity is changing every moment because the directionit is going is changing. Speed is uniform, but velocity isn't. As asked, uniform speed is a uniform distance per unit of time. And this will yield a uniform distance per unit of time in its velocity, but the direction vector may be uniform or it may be changing each moment, as illustrated.
