Impulse/math practice
What is impulse?
A force during a time interval
Mass in motion
Momentum
What is Inertia?
The property of matter that causes something to resist any change of motion.
Mass unit
kg
What is Impulse going the same direction of?
The force
Is Momentum a vector or scalar?
In the equation F=ma what does the a stand for?
Acceleration
Impulse symbol
I
Impulse equation
I=Ft
Momentum equation
P=mv
The sheet applies a smaller force over a longer period of time.
Momentum symbol
P
What does Impulse depend on?
What does the v stand for in P=mv
Velocity
What are the equations I=Ft and I=pf-pi combined>
Ft=pf-pi
Ns and kgm/s
A cart receives an impulse of 20 Ns. If the force of the push was 5N, how much time was the cart being pushed?
4s
A car has a momentum of 1500kgm/s. If the car has a mass of 25kg, how fast was the car traveling?
