CHAPTER 5 HW Part 1– WORK, ENERGY AND POWER Work p
... Work p. 160-163 (W = Flld or W = Fdcosθ, where θ is the angle between F and d) 1. A toddler pushes a cart across a floor with a force of 32 N parallel to the floor for a distance of 1.5 m. If the baby pushes the cart at a constant velocity, how much work was done by: a) the baby b) friction c) total ...

... • Mass and distance • The greater the mass of an object=the larger the gravitational force it exerts on the other. • If the distance between two objects is doubled, the gravitational force bewteen them decreases to ¼ its original value • If the distance is tripled, the gravitational force decreases ...

... A football is thrown at some angle. Neglecting air resistance, the horizontal velocity is constant, and the vertical velocity decreases (on the way up) then increases (on the way down), just as in the case of a vertical projectile. The combined motion produces a parabolic path. ...

Goal #2 – Motion and Forces
... A graph of distance (displacement) vs. time can show the velocity of an object. Divide distance by time. Velocity is measured in meters/second (SI unit). Objects that are travelling at a constant speed are said to have uniform velocity. (They are not speeding up or slowing down.) Acceleration can be ...

Force - Back
... An object at rest remains at rest and an object in motion will continue moving at a constant velocity unless acted on by unbalanced forces. ...
