  • Does acceleration increases as mass increases Why?

    The acceleration of an object depends directly upon the net force acting upon the object, and inversely upon the mass of the object. As the force acting upon an object is increased, the acceleration of the object is increased. As the mass of an object is increased, the acceleration of the object is decreased. How […]

  • What was removed from the AP Physics 1 exam?

  • Why will the rider on a roller coaster feel heavier at the bottom of a loop and lighter at the top of a loop?

    Roller coasters are generally designed to have non-zero but fairly small normal forces at the top, so a rider feels almost weightless. At the bottom of the loop, the apparent weight can be considerably larger than mg, so a rider feels much heavier than usual. How is physics used in amusement parks? A roller coaster […]

  • Why is physics used to study car crashes?

    Focusing on the distinction between force and energy can help explain the physics involved. Car crashes are clear examples of how Newton’s Laws of Motion work. His first law of motion, also referred to as the law of inertia, asserts that an object in motion will stay in motion unless an external force acts upon […]

  • How does a car crash show Newton’s third law?

    Newton’s Third Law Example Car crashes are an example of Newton’s Third Law. The car exerts a large force on the wall and the wall then exerts a large force back onto the car. Civil engineers are always trying to think of new ways to make highways safer. What is the physics behind car crashes? […]

  • What is the importance of free-body diagram?

    The drawing of a free-body diagram is an important step in the solving of mechanics problems since it helps to visualize all the forces acting on a single object. The net external force acting on the object must be obtained in order to apply Newton’s Second Law to the motion of the object. What is […]

  • What is the science behind throwing a football?

    How is physics used in football? There are many forces involved in the game of football. These are: Force of Gravity, Normal Force, Force of Friction, and Applied Force.
