... continue in a straight line, but it doesn’t. Why not? Newton 2nd Law: 1. If a net force gets larger on an accelerating mass, how will the mass respond? 2. If a truck loaded with bricks is accelerating, but many bricks fall off during acceleration, what will now happen to the motion of the truck? 3. ...

3 Newton`s First Law of Motion—Inertia
... We can define mass and weight as follows: • Mass is the quantity of matter in an object. More specifically, mass is a measure of the inertia, or “laziness,” that an object exhibits in response to any effort made to start it, stop it, or otherwise change its state of motion. • Weight is the force of ...

Externally fed accretion on to protostars
... There is no reason why the dense core’s accrual of gas should cease once that object has produced a central star. Prior to this event, the core had an extended period of slow evolution. Thus, the internal accretion rate on to the protostar has had ample time to adjust so as to match the external rat ...

A car moves because a reaction to the force exerted by the tire produces a force by the road on the wheel. • What is then driving force of a rocket? When an explosion occurs in a spherical chamber with fue ...

Newton`s Law of motion 1
... Gravitational mass is measured by such method, e.g. spring balance. Measuring the mass (inertia mass) Mass can be defined as the ‘ amount of matter’ in an object. But considering Newton’s 2nd Law of motion, m = FN / a, mass has a new meaning – “Inertia”. Inertia is the resistance of an object to a c ...
