What is force x velocity?
Calculating Power Since work is force times displacement (W=F*d), and velocity is displacement over time (v=d/t), power equals force times velocity: P = F*v.
How do you find the force of a velocity time graph?
Velocity = Area under the graph/ mass of object. Area under the graph gives you impulse (force x time), splitting up force to isolate velocity you get mass x velocity (f=ma; v=at). Divide by mass of the object to get velocity.…
What is the slope of a force-velocity graph?
The slope of a velocity graph represents the acceleration of the object. So, the value of the slope at a particular time represents the acceleration of the object at that instant.
What is the slope of a force x time graph?
With a force-time graph, the slope isn’t important; however, area is important. The area under a force-time graph is force multiplied by time, which is a quantity called impulse. Impulse is equal to the change in momentum of an object.
What is force x acceleration?
According to Newton s Second Law of Motion, also known as the Law of Force and Acceleration, a force upon an object causes it to accelerate according to the formula net force = mass x acceleration. So the acceleration of the object is directly proportional to the force and inversely proportional to the mass.
What is relation of power with force and velocity?
In the straightforward cases where a constant force moves an object at constant velocity, the power is just P = Fv. In a more general case where the velocity is not in the same direction as the force, then the scalar product of force and velocity must be used.
What is the slope force vs velocity squared graph?
The slope of Fc/v^2 is basically m which represents the mass/r which is the radius. So we can deduct that the slope of the graph for the equation Fc vs. v2. represents the ratio between mass and the radius (lenght of the chain in this case.
What does the slope of a force distance graph represent?
1 Answer. Literally the slope means force per unit distance or force gradient. An example is spring constant.
What is force x time?
force x time = momentum. To answer your original question, then, the difference between force and momentum is time. Knowing the amount of force and the length of time that force is applied to an object will tell you the resulting change in its momentum.
What does the slope of a force vs stretch graph represent?
We should need more force to stretch the spring for larger displacements. The slope of this graph represents the spring constant k, which indicates the stiffness of the spring.
Is force mass x velocity?
F=MA is describing a force, while P=MV is actually momentum. The first equation states that a Force is equal to Mass times Acceleration, or Newton’s second law of motion. The second one states that Momentum (P) is equal to Mass times Velocity. Objects that have momentum are not necessarily being acted on by a force.
What does P VI mean?
electric power
The formula for electric power is given by. P = VI. where, P is the power. V is the potential difference in the circuit.
What is the area under a force vs time graph?
The impulse equals the area under a force versus time graph, and this is extremely useful to know, because now in this section, where the force was varying, we can still use this, we can just find the impulse by determining the area under that curve.
What is the relationship between velocity squared and centripetal force?
Note that the centripetal force is proportional to the square of the velocity, implying that a doubling of speed will require four times the centripetal force to keep the motion in a circle.
What does the slope of a force vs mass graph represent?
The slope of this graph is the acceleration and it is positive. The net force is proportional to the acceleration, so this graph implies a positive net force on the cart.
What is the slope of force and displacement graph?
Mathematically, F=kx. where k is the spring constant. Thus the slope of the force vs displacement graph is xF=k.
How to find ‘velocity’ from ‘Force vs. time’ graph?
– F=dp/dt then , Fdt = dp – Impulse= average force × time – Impulse of a force is a measure of the total effect of the force. – Impulse = change in momentum – According to Impulse momentum theorem States that linear momentum can be reduced by smaller force for a longer time and longer force for a shorter time.
How to find velocity from force and distance?
force
What is the force velocity curve?
Maximum strength. These are your slower,maximally forceful movements,typically lifts performed at above 80% of 1RM.
What are velocity vs. time graphs?
Displacement Time Graph. Displacement of an object is defined as how far the object is from its initial point.
