The change in momentum of an object is equal to the question 4 options: force acting on it times its velocity. impulse acting on it. change in velocity of the object.

impulse acting on it

Explanation:

The impulse is defined as the product between the force applied to an object (F) and the time interval during which the force is applied ():

We can prove that this is equal to the change in momentum of the object. In fact, change in momentum is given by:

where m is the mass and is the change in velocity. Multiplying and dividing by , we get

and since is equal to the acceleration, a, we have

And since the product (ma) is equal to the force, we have

which corresponds to the impulse.

are their multiple choices ?

explanation:

the simple machine has three main features. they are:

fulcrum is the center point or pivot point of the machine. effort is input force/ applied force. load is external force/ output.

the keisha 's machine labels are

x : load

y: fulcrum

z: lever
