Unformatted text preview: Power= work/ time Power= force x velocity Power= torque x angular velocity Power= torque x angular velocity Power= force x velocity SI UNIT Power= joule per second or wattStatic friction exerts torques on the rollers and hence is what makes them rotate in the first place Coasting forward: Linear momentum Energy is directionless, it is not a vector quality Linear momentum (momentum) – is the measure of an objects translation motion its tendency to continue moving in a particular direction Momentum= mass x velocity The greater an obejects mass and velocity the more momentum an object has in the direction it is moving SI UNIT Momentum= kilogram meter per second Impulse a force exerted on an object for a certain amount of time Impulse= force x time Impulse= large force x short time = small force x long time If the momentum gained by one object is equal to the momentum lost by anther object, you can say that momentum was transferred...
