Chapter 4 - Forces and Newton`s Laws of Motion w./ QuickCheck
... What do forces do? - They cause an object to move, accelerate An object pulled with a constant force experiences a constant acceleration (both pointing in the same direction) Acceleration is directly proportional to the force (F ∝a) Acceleration is inversely proportional to an object’s mass (a ∝ 1/m ...

Relationship Between Impulse and Momentum - McGraw
... Newton combined an object's mass and velocity in an expression which he called “quantity of motion.” We now define this product of mass and velocity as momentum. From Newton's second law we see that an object's velocity changes when it is acted upon by an unbalanced force. This would also mean then ...

... 21. Eq. 7-15 applies, but the wording of the problem suggests that it is only necessary to examine the contribution from the rope (which would be the “Wa” term in Eq. 7-15): Wa = (50 N)(0.50 m) = 25 J (the minus sign arises from the fact that the pull from the rope is anti-parallel to the directio ...
