The ability to change the motion of the moving object depends primarily on these two factors.
Mass of the object
Velocity of the object
Size of the object
Shape of the object
The product of the mass and velocity of an object is called
Momentum
Weight
Impulse
Theta
The equation seen here
Momentum = Mass x Velocity
Power = Momentum x Velocity
Propulsion = Movement x Velocity
Impulse = Mass x Force
The momentum of a 1.00 kg ball moving with a velocity of 15.0 m/s will be
15 kg m/s
1.5 kg m/s
150 kg m/s
1500 kg m/s
If we wish to change the momentum of an object in motion, we must
apply a force.
give the object inertia.
change the shape of the object.
instantly stop the object.
Applying a force to an object can change its momentum. The product of force x time (which the force acts) is called:
Impulse
Impedo
momentum
Theta
Here we can see the impulse equation. We should read this as:
Impulse = change in momentum
Momentum = change in impulse
Feet = triangle m-vee
Force = Impulse
Clearly it is safer to jump from a ladder onto a mound of hay rather than onto bare concrete. Which explanation is best as to why this is so.
The impulse occurs over a longer time period but with a lower force.
Less momentum is lost when jumping onto hay.
There is less impulse when jumping onto hay.
There is a greater change of momentum when jumping onto concrete.
If we apply an impulse to an object
it will always speed up.
it will always slow down.
it will experience a change in momentum.
the mass of the object will change.
A 3.5 kg and a 7.0 kg bowling ball are each dropped from a high tower. Which experiences the greatest impulse when striking the ground beneath the tower?
The 7.0 kg bowling experiences greater impulse.
The 3.5 kg bowling ball experiences the greater impulse.
Both balls experience the same impulse because their velocities are equal.
Neither ball experiences an impulse when striking the ground.
