When did AP classes begin?

In the 1955–56 school year, it was nationally implemented in ten subjects: Mathematics, Physics, Chemistry, Biology, English, History, French, German, Spanish, and Latin. The College Board, a non-profit organization based in New York City, has run the AP program since 1955. Is AP Physics 1 the hardest AP? AP Physics 1 consistently tops the list … Read more

How is centripetal force related to tangential velocity?

Centripetal force is perpendicular to tangential velocity and causes uniform circular motion. The larger the centripetal force Fc, the smaller is the radius of curvature r and the sharper is the curve. The lower curve has the same velocity v, but a larger centripetal force Fc produces a smaller radius r ′ r ′ . … Read more

What is an example of electric potential?

Electric potential is electric potential energy or work per unit of charge. For example, a 1.5 V battery has an electric potential of 1.5 volts which means the battery is able to do work or supply electric potential energy of 1.5 joules per coulomb in the electric circuit. How do you calculate electric potential? q … Read more

How do you find the initial velocity of an elastic collision?

How do you find velocity from a collision? From the conservation of momentum, the equation for the collision between two objects is given by: m1v1 + m2v2 = m1v’1 + m2v’2. From this expression, the initial and final velocities can be derived. How do you find the initial momentum after a collision? Use the momentum … Read more

What class is AP Chemistry equivalent to in college?

The AP Chemistry course is designed to be the equivalent of the general chemistry course usually taken during the first college year. Do you have to be AP certified to teach AP classes? Advanced Placement (AP) subjects are taught by qualified high school teachers. The College Board does not require teachers to have special training … Read more

Why do clothes stick together in the dryer physics?

When you dry clothes in the dryer, different fabrics rub together, and electrons from a cotton sock (for instance) may rub off onto a polyester shirt. That’s why clothes sometimes stick together and make sparks when you pull them apart. You may have used antistatic sheets in your dryer. What happens to electrons when clothes … Read more

How do you describe motion kinematics?

Kinematics is the branch of mechanics concerned with the motions of objects without being concerned with the forces that cause the motion. In this latter respect it differs from dynamics, which is concerned with the forces that affect motion. Is kinematics and motion in one dimension same? Answer: No. It is now possible to describe … Read more

Can you use kinematic equations in simple harmonic motion?

Kinematics can be used not only to study linear motion, but also other motion, including simple harmonic motion. Simple harmonic motion is any motion where a restoring force is applied that is proportional to the displacement, in the opposite direction of that displacement. What is the equation for simple harmonic motion? That is, F = … Read more
