Impulse and momentum have the same units; when an impulse is applied to an object,
the momentum of the object changes and the change of momentum is equal to the impulse
.
Does a moving object have momentum?
All moving objects have what Newton called a “quantity of motion.” Today it’s called momentum. Momentum is a characteristic of a moving object that is related to the
mass and velocity
of the object. The momentum of a moving object can be determined by multiplying the object’s mass by its velocity.
Does a moving object have impulse or does it have momentum?
Answer: Impulse is the product of the average force and the short time interval for which it acts and causes a change in momentum of a body, A moving object can experience an impulse if a force acts
on it and changes its momentum
.
What is difference between impulse and momentum?
Momentum is mass in motion, and any moving object can have momentum. An object’s change in momentum is
equal to
its impulse. Impulse is a quantity of force times the time interval. Impulse is not equal to momentum itself; rather, it’s the increase or decrease of an object’s momentum.
Which object has the greatest acceleration?
Explain.
Car A
has the greatest acceleration. The velocity change of each car is the same. (They start with the same velocity and each finish with zero velocity.)
Can a lighter object have more momentum than a heavier one how?
Can a lighter object have more momentum than a heavier one? How?
No
, because momentum is independent of the velocity of the object. No, because momentum is independent of the mass of the object.
How do you know what has the greatest momentum?
The momentum of an object varies directly with the speed of the object. Two objects of different mass are moving at the same speed;
the more massive object
will have the greatest momentum. A less massive object can never have more momentum than a more massive object.
Why doesn’t a heavy object accelerate more than a light object when both are freely falling?
Why doesn’t a heavy object accelerate more than a lighter object when both are freely falling? o
Because the greater mass offsets the equally greater force
; whereas force tends to accelerate things, mass tends to resist acceleration.
Which ball will be traveling faster when it hits the ground?
Which ball will be traveling faster when it hits the ground? –
Ball 1 and ball 2
will be traveling equally fast when they hit the ground.
Which formula is used to find an object’s acceleration?
Acceleration (a) is the change in velocity (Δv) over the change in time (Δt), represented by the equation
a = Δv/Δt
.
What is an example of impulse momentum?
Impulse is a certain amount of force you apply for a certain amount of time to cause a change in momentum. That is why it is F*t. For example, when you
hit a ball with a cricket bat
, you apply a force for a time(a very short period in this case) to cause a change (or transfer) of momentum in the ball.
How do you calculate impulse examples?
Impulse is a certain amount of force you apply for a certain amount of time to cause a change in momentum. That is why it is F*t. For example, when you

How do you impulse?
All that you need to do to launch yourself into the air is to throw the grenade
at your feet
. Once you throw it at your feet it will launch you into the air depending on where you are standing and in which direction.
Does a heavier object have more momentum?
The momentum of an object varies directly with the speed of the object. Two objects of different mass are moving at the same speed;
the more massive object will have the greatest momentum
. A less massive object can never have more momentum than a more massive object.
Do heavier objects accelerate faster?
Heavier things have a greater gravitational force
AND heavier things have a lower acceleration. It turns out that these two effects exactly cancel to make falling objects have the same acceleration regardless of mass.
