... The first graph(net force and the rate of acceleration graph) is a linear graph meaning the relationship between the net force and the rate of acceleration is proportional to each other. The slope of the line is equal to the mass of the cart. The mass of the cart was 0.53 and the slope was approxim ...

... Note that we take moments about point P. This is because there is a third force which acts on the shelf; this is the contact force (or ‘reaction’) of the wall on the shelf. We do not know its magnitude or direction but, since it acts through point P, it has no turning effect about P. ...

... An object with twice the amount of matter accelerates only half as much in response to the same force. The more matter an object has, the more it resists accelerating in response to the same force. The tendency of an object to resist a change in its velocity is called inertia. The mass used ...

... What? —When there isn’t force, objects can still make with constant velocity? How can the net force of a car be zero if it is moving? Newton’s first law can lead to confusion if students place it in an unintended context. They might be misled by the need to exert a force on an object to bring it up ...

If the ball has a mass of 0.060 kg and is in contact with the racket for about 4 ms (4x10-3 s), estimate the average force on the ball. Would this force be large ...
