Acceleration can either be negative or positive. When an object slows down, the acceleration is in the opposite direction as velocity. In such... View Article
An object that is moving only because of the action of gravity is said to be free falling and its motion is described by Newton's second law of motion.... View Article
Acceleration in physics is defined as the rate of change of velocity. If the initial and final velocities along with the time duration is given,... View Article
When a collision occurs in an isolated system, the total momentum of the system of objects is conserved. Provided that there are no net external... View Article
The angular momentum in uniform circular motion is not zero. The angular momentum in the motion is equal to It has a constant direction... View Article
Momentum is important in Physics because it describes the relationship between speed, mass and direction. It also describes the force needed to... View Article
Newton’s third law of motion implies that the total momentum of a system not acted on by outside forces is conserved. The total momentum in the... View Article
From Newton’s second law of motion, we know that if a force is applied to a body then the body accelerates in the direction of the applied force.... View Article
The angular momentum of an object moving in a circle with radius 'r' is the product of the mass, velocity or speed of rotation, and the radius of... View Article
Airbags use the principle of momentum to reduce the damage during a collision. The air bags in automobiles minimize the effect of the force on an... View Article
Both momentum and impulse revolve around the Newton’s second law of motion. Momentum is the product of mass and velocity. However, impulse... View Article
