What does a constant velocity graph look like?
What does a constant velocity graph look like? Constant velocity means the velocity graph is horizontal, equal to 11.11 m/s at all times. A constant velocity means the position graph has a constant slope (of 11.11 m/s). It’s a straight line sloping up, and starting below the origin. The displacement is the area under the […]
How do you calculate your weight on Neptune?
How do you calculate your weight on Neptune? Being that it takes the weight of an object on earth and converts it to the weight on Neptune, the formula is Weight on Neptune= (Weight on Earth/9.81m/s2) * 11.15m/s2. To find the weight on Neptune, we divide the weight on earth by the earth’s force of […]
