... In most situations there will be more than one force acting on an object. If we want to calculate the acceleration of the object we must first find the unbalanced force. The combination of forces is known as the resultant. Example: The engine of the car provides a driving force of 2 500 newtons. The ...

... contact? This occurs when the normal force goes to zero or, equivalently, when all the weight is used to achieve circular motion. Fc = mg = m v2 /r v = (gr)½ (just like an object in orbit) Note this approach can also be used to estimate the maximum walking speed. Physics 207: Lecture 12, Pg 12 ...

... The initial velocity is horizontal; the magnitude is 10 m/s. Then the equation of motion along horizontal axis has the following form: After 0.2 seconds the dart hits the target. From this condition and from the above equation we can find the distance between the point where the dart is released and ...

Section 9.1 Impulse and Momentum
... Momentum - product of an object’s mass and velocity. It is a vector quantity that has the same direction as the velocity of the object. It is denoted by “p” (lower case). It is mass in motion. The unit for Momentum is kg m/s. To find Momentum you use p = m*v Δp = mΔv FΔt = mΔv = mvF – mvI = Δp = pF ...
