8 Unit 1: …We tend to use calculus when the force or the mass is variable, like with a rocket! I mean, doesn't it take a lot of effort(energy) to slow down the object and then accelerate it again to 4m/s on the opposite direction rather than slow down it a little bit so that it moves 4m/s to the left? Question 3Unit 1: Kinematics You'll begin your study of motion and the quantities associated with the motion of an object: position, velocity, acceleration, and time. So, as this mass slides up to a higher point on the ramp, the gravitational potential energy increases, but the mass is gonna slow down, so the kinetic energy's gonna decrease. In other words, the amount of Joules per second that are transferred, and the name given to a Joule per second is a Watt. If you pull straight up on the string with MORE than enough force to lift it, the object moved off the ground and is given a vertical displacement.

If you could tell me where I messed up, it would be greatly appreciated. Equal to the force exerted. Between zero and three meters, the work done is gonna be negative, and the area of this triangle is gonna be one-half the base times the height which is one-half times three meters time negative six Newtons which is negative nine Joules of work done, and the area under this triangle, between three and five seconds, would again be one-half base times height, which is one-half times two meters times height of four Newtons which is positive four Joules of work done. Correct; one could also say that the direction of the velocities does not matter because we are looking for a scalar quantity, that is, kinetic energy.

Positive work is done by a force parallel to an object's displacement. And even though work is not a vector, it can be positive or negative. The length of the ramp with the angle θ is longer than the ramp with angle 2θ, so if the boxes are accelerated at the same rate with no friction, the box on the right has farther to travel.
