  • What is a vector quantity?

    vector, in physics, a quantity that has both magnitude and direction. It is typically represented by an arrow whose direction is the same as that of the quantity and whose length is proportional to the quantity’s magnitude. Although a vector has magnitude and direction, it does not have position. How do you solve vectors in […]

  • Why is the letter J used for impulse?

    A change in momentum is known as an impulse. The vector quantity for impulse is represented by the letter “J”, and since it’s a change in momentum, its units can be one the same as those for momentum, [kgยทm/s], and can also be written as a Newton-second [Nยทs]. How do you calculate impulse? Impulse Formula […]

  • How does weight affect roller coasters?

    The larger the mass, the larger the momentum, and the more force you need to change it. Mass does not make a roller coaster go faster but it does make it harder to slow down. This is why amusement parks test roller coasters with dummies filled with water. Does the roller coaster ever get higher […]

  • How much force is in a football collision?

    COLLISIONS IN A single game of American football have a similar force to that of 62 car crashes, according to new research. How much force is behind a football hit? But a DB’s mass combined with his speed — on average, 4.56 seconds for the 40-yard dash — can produce up to 1600 pounds of […]

  • What are the three types of charges?
