Impulse of a Force-Time Graph In real life, forces are often not constant and will vary over time If the force is plotted against time,?the impulse is equal to the area under the force-time ...
Force & Momentum Force is defined as the?rate of change of momentum?on a body The change in momentum is defined as the final momentum minus the initial momentum These can be expressed as...
The Principle of Conservation of Momentum The principle of conservation of linear momentum states: The total momentum before a collision = the total momentum after a collision provided no ex...
Linear Momentum Linear momentum (p) is defined as the product of mass and velocity Momentum is the product of mass and velocity Momentum is a vector quantity - it has both a magnitude...
Newton's Third Law Newton's Third Law states: If body A exerts a force on body B, then body B will exert a force on body A of equal magnitude but in the opposite direction This means that ev...
Newton's Second Law Newton's Second Law states that: The resultant force on an object is equal to its rate of change in momentum. This change in momentum is in the?same direction?as the resu...
Newton's First Law Newton's First Law states: A body will remain at rest or move with constant velocity unless acted on by a resultant force If the forces on a body are balanced (the resulta...
Required Practical: Determination of g Aims of the Experiment The overall aim of the experiment is to calculate the value of the acceleration due to gravity,?g This is done by measuring the ...
Terminal Velocity For a body in free fall, the only force acting is its weight and its acceleration?g?is only due to gravity. The drag force increases as the body accelerates This increase i...
