Term1/10

Momentum is defined as the rate at which work is done true or false

Definition1/10

False

Term1/10

What does the impulse-momentum theorem state

Definition1/10

Impulse equals change in momentum. "Apex" The final momentum of any object (or collection of objects) must equal to its initial momentum plus any impulse imparted to the object (or collection of objects).

Term1/10

Inclined plane makes work easier by increasing the distance and decreasing the

Definition1/10

force

Term1/10

If you want to lift a 5-kg box to a height of 1 meters how much work must be done

Definition1/10

98 j

Term1/10

When a deck of cards slips out of your hands and falls to the ground gravity does work on it

Definition1/10

True - apex =)

Term1/10

When only mechanical energy acts on an object what is conserved

Definition1/10

gravity

Term1/10

What are the ways the expression for impulse can be expressed

Definition1/10

(^ is the triangle thing)

*Impulse= F^t

*Impulse=^p

Term1/10

What is an example of conditions not producing work

Definition1/10

the momentum must be greater than the force . the force may be very large

Term1/10

Spaceship 1 and Spaceship 2 have equal masses of 150 kg Spaceship 1 has a speed of 0 and Spaceship 2 has a speed of 6 They collide and stick together What is their speed

Definition1/10

3 m/s

Term1/10

What is the Ideal Mechanical Advantage when a screwdriver with a handle of radius 1.2 cm is used to remove a screw in the back of a computer and the screw moves out 0.20 cm on each turn

Definition1/10

There is no advantage whether the handle is 1.2 cm or 10 cm, the screw will still only make one revolution. The reason being is that both the screw driver and the screw become part of the whole. The only increase in the screws revolutions is if the screw driver is geared to make more than one turn of the screw.
