Strictly speaking, you would say that a force acts on a system and the impulse of that force corresponds to the change in momentum of the system due to the action of the force. More mathematically, the impulse of a force is defined as the integral of that force with respect to time over the time period that the force acts.
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.
Impulse = [(change in momentum)/time]*time[(change in momentum)/time] = ForceAnd when force acts for a period of time, that impulse changes the momentum of the object.You can also rewrite the impulse equation as: I = F*tHowever, for change in momentum times time, the units would be (kg*m/s)*(s) = kg*m. These units are not in common usage.
Yes, the momentum of a system will change when a net force acts on it. According to Newton's second law of motion, the change in momentum of a system is directly proportional to the net force acting on it.
no
Because impulse is the integral of the force over the time during which it was applied. Graphically, this is the area under the curve of force against time.Force is rate of change of momentum. Even if you hit a brick wall you impart momentum to some of the atoms in it. The area under a graph of force against time is mathematically speaking the integral of the force with respect to time, as stated above. So it is the integral of the rate of change of momentum. But the integral of a rate of change of anything, is simply the total change. In this case, the total change of momentum. For a large force applied for a very small time, that is called (defined to be) an impulse, and it results in a change of momentum. Strictly it doesn't have to be a small time for this to be true, but impulses are generally imagined as being short time events.
Impulse is change of momentum, which is force x time over which the force acts. Original momentum = mv, final momentum =0, so impulse is in this case mv.
Impulse-momentum theorem
Impulse-momentum theorem
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.
Impulse is a measure of the change in momentum, not its equivalence. Momentum is the product of an object's mass and velocity, while impulse is the product of force and time over which the force acts. So, they are related but not equal.
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.
Impulse = [(change in momentum)/time]*time[(change in momentum)/time] = ForceAnd when force acts for a period of time, that impulse changes the momentum of the object.You can also rewrite the impulse equation as: I = F*tHowever, for change in momentum times time, the units would be (kg*m/s)*(s) = kg*m.

Yes, if a net force acts on a system, the momentum of the system will change. This change in momentum is directly proportional to the magnitude of the force and the time for which the force is applied.
Yes, the length of time a force acts on an object affects the strength of the impulse produced. A longer application of force increases the impulse applied to the object, resulting in a greater change in momentum. This relationship is described by the impulse-momentum theorem.
Two reasons. Recall impulse is the change in momentum. First the momentum is a vector. So imagine a triangle. One side is the initial momentum (with one direction), the second side is the final momentum (with a potentially different direction) and the third side is the impulse (or change in momentum). The other way to look at this is in terms of what causes the change in momentum. This is how impulse is generally described. The impulse can be defined as the average force acting on the particle multiplied by the time interval over which the force acts. This is sometimes represented as the integral of the force. As force is a vector so is the impulse caused by this force.
The quantity that combines the strength of a force with how long it acts on an object is called impulse. Impulse is calculated by multiplying the force by the time over which it acts on an object. It represents the change in momentum of the object.
An impulse of 15 units is equal to the change in momentum of an object. Impulse is calculated as the product of force and the time duration over which the force acts. Therefore, if an impulse of 15 units is applied, it means that the object's momentum has increased or decreased by 15 units as a result of that force over the specified time.
