What is the nature of the displacement time graphof a body moving with constant acceleration?
The equation which covers this is s = ut + at2/2 where s is distance (ie displacement), u is initial velocity, t is time and a is the acceleration. This is a parabola with an initial (t=0) slope equal to u. The above equation comes from simple integration of the velocity versus time equation v=u+at, using an origin for distance s=0 at t=0.
What line segments on a velocity versus time graph is physically impossible?
A vertical line on a velocity vs time graph is physically impossible.
How do you work out velocity acceleration?
v2 = v02 + 2a(delta x)v = sqrt(v02 + 2a(delta x))This is based on the assumption that there is constant acceleration.Another way to find velocity is using a little Calculus, this method is better since it does not assume constant acceleration, therefore this would work even if there is a change in acceleration.Since v = dx/dt, you can differentiate position with respects to time to find instantaneous velocity, given that you do know the time.And dv/dt = a, therefore dv = a x dt, integrate both sides you get velocity. This approach again requires the knowledge of time.
What is initial force?
action (versus reaction, the opposing force to action). ================
What is the velocity of an object at any given instant in time is known as?
It is called instantaneous velocity and is the slope of the line tangent to the point on the position versus time graph. It also can be found by differentiating position with respect to time (i.e. dx/dt)Instantaneous Speed
Velocity versus time?
Yes.
What does the slope of a distance versus time represent?
velocity
What type of motion is occurring when the slope of a line is not zero?
Assuming the graph is for displacement versus time, the motion should be constant velocity. If velocity versus time motion is constant acceleration
Will the graph of instantaneous velocity versus time have a Y-axis intercept of zero?
If you started at zero velocity, yes.

What does the slope of distance-versus-time graph represent physically?
instantaneous magnitude of velocity
What does the slope of they curve on a velocity-versus-time graph represent?
The rate of change in accelleration.
Escape velocity of earth versus escape velocity on Uranus?
EV on Earth is 11.186 km/s EV on Uranus is 21.3 km/s
What does the slope of distance versus time graph represent physically?
Tangent of the slope at any point = velocity
What are the pros and cons of concrete versus steel in building framework?
One of the pros of concrete versus steel in a building framework would be that it is cheaper to use concrete. One of the cons would be that it is not as safe to use concrete.
Is acceleration the slope of the velocitys vs the time graph?
Yes, acceleration is the slope of a velocity versus time graph.
