The product of (force x time) is the quantity called 'impulse'. It has the same
units as momentum and, indeed, an impulse imparted to an object increases its
momentum by that amount.
In the metric system, it's easy. A newton-second is a kilogram-meter per second.
But in this case, all you have for impulse is something called a "poundal-second",
which I have no idea what other unit that may be equivalent to. I don't even know
what the unit of momentum is in the 'customary' system. Foot-pound per second ?
Slug-mile per hour ? Who knows ?
Impulse
Force times time is a quantity known as impulse. It represents the change in momentum of an object when a force is applied over a period of time. Impulse is calculated as the product of force and the time over which the force acts.
they both are always making time and is always in motion
To determine the constant force required to accelerate a 9.5 kg mass at 10 miles per second, you need to convert the acceleration to meters per second squared. 10 miles per second is approximately 16,090 meters per second. Then, you can use the formula F = ma, where F is the force, m is the mass, and a is the acceleration, to calculate the force required.
Force = mass x acceleration = kg(m/s^2) or N Momentum = mass x change in velocity = kg(m/s) or Ns The units of impulse are the same as momentum's because impulse is just the change in momentum.
time
The product of force and time is impulse, which is a measure of the change in momentum of an object. It is calculated by multiplying force by the time over which the force acts on the object.
Impulse - APEX ! =)
No, impulse is not the product of average applied force and the duration of the force. Impulse is the integral of the force with respect to time.
Impulse is the product of a force and the time interval during which that force acts. It represents the change in momentum of an object.
The only equation that comes to mind is the one for impulse. An impulse is a force applied for a limited time. > Velocity change = (force * time) / mass > Example : A 10 kg mass is travelling at 100 m/s, a force of 100 newtons is applied for 5 seconds in the same direction as the motion, calculate the new velocity. > Velocity change = (100 * 5) / 10 = 50 metres per second Add to original velocity = 100 + 50 = 150 metres per second
Impulse
Same as the unit of momentum - an impulse is a transfer of momentum. Velocity x mass. Or the equivalent force x time.
Yes, force is equal to the rate of change of momentum with respect to time. In the case of a constant mass, force can be expressed as the product of mass and acceleration according to Newton's second law (F = ma).
Force times time is a quantity known as impulse. It represents the change in momentum of an object when a force is applied over a period of time. Impulse is calculated as the product of force and the time over which the force acts.
Velocity is not the product of force and time. Velocity is the rate of change of an object's position with respect to time and is influenced by forces acting on the object. The formula for velocity is v = d/t, where v is velocity, d is distance, and t is time.
Time Force is a time and attendance software. Many different businesses and companies might utilize the Time Force software to help track employee hours.
