What is equal to an impulse of 20 units?
Force=25,time=0.8Force=0.1time=200Force=10,time=2
What time what equals - 60?
7.74596669241483 (There is no whole number that if multiplied by itself will equal sixty)
Which of the following is equal to an impulse of 15 units?
Force = 10, time = 3 Force = 0.1, time = 300 apex-Force = 7.5, time = 2
The principal is multiplied by the rate and then multiplied by the?
Time
What is a change in velocity in given period of time?
Change in velocity = Velocity at the end of the period minus velocity at the start of the period.
This is equal to the initial velocity plus acceleration multiplied by time?
That's the velocity at any time.
How is impulse relative to momentum?
impulse (force x time) is equal to momentum (mass x velocity); Ft=mv
Is it correct to say that force multiplied by time is equal to the change in mass multiplied by velocity?
8 multiplied by 6 equals 48
Is impulse a vector?
Yes, Impulse is a vector.By definition impulse is a force F, multiplied by the amount of time dt thatis applied to a body with mass m, to give him an increment of velocity dv.F dt = m dv
When a body is moving with uniform velocity what is difference between distance and time?
the distance will be equal to the time multiplied by a factor which is the speed.
What factors are used to calculate impulse?
impulse= the change in momentum or force multiplied by time
Why is it incorrect to say that impulse equals momentum?
Impulse is the change in momentum. Therefore Impulse is only equal to momentum if the initial momentum was equal to zero. Its the same phenomenon as position and displacement. Impulse= final momentum-initial momentum= mv - mv_0= Force * Time Where m is the mass and v is the velocity.
How can impulse increase?
Impulse is denoted as a change in momentum. Momentum has the units of kilogram meter per second. Which is mass times velocity. So you can decrease the time and increase the velocity to increase the impulse.
Equation for calculating velocity when acceleration and time are known?
velocity=acceleration multiplied by time
A 0.3 kg book is struck with a force of 150 N If the ball was in contact with the ball for 0.02 s What is the ball's velocity?
To solve this problem we use the impulse momentum theory that tells us that the change in the momentum of an object (its mass times its velocity) is equal to the impulse that acts on it (a force multiplied by a time). Applying this theory to this problem we get the equation .3kg * v = 150N * 0.02s. Solving this equation for v we get that v must equal 10 m/s, which is therefore the new speed of the ball.
Does the length of time that a force acts on an object that have any effect on the strength of the impulse produced explain?
Yes, it does. Assuming a constant force, the impulse is equal to the force multiplied by the time the force acts. (If it isn't constant, you will of course use an integral instead.)
Distinguish between impulse and momentum which is force x time and which is inertia in motion?
Impulse is equal to the change in momentum: definition of impulse is Force x time. When a force is applied to an object for a certain amount of time its momentum (mv) will increase because it is accelerating due to the force on it. Force x time = the change in MV (change in momentum) This is just a restatement of Newtons law F=MA it is actually derived directly from F=MA
