American teens have a quick and easy access to A: drivers license B: cars C: both a and b are correct

Ignore friction and air resistance. If the total mass of the roller coaster cars is 800kg, and the 50,000 N of gravitation force are acting on the roller coaster cars, what is the acceleration of the roller cars?

Liquids and air resistance are always: A. fluid forces B. support forces C. applied forces D. tensional forces

A net force of 3000 N is accelerating a 1200 kg elevator upward. If the elevator starts from rest, how long will it take to travel up 15 m?

The frequency of a given region of the electromagnetic spectrum ranges from 3 _ 1016 _ 3 _ 1019 hertz. Which type of wave is found in this region?

A student is testing the kinematic equations for uniformly accelerated motion by measuring the time it takes for light-weight plastic balls to fall to the floor from a height of 3 m in the lab. The student predicts the time to fall using g as 9.

Newton's Second law of Motion (F = ma) is one of the basis of forces and motion. How is it very similar to his First law and why is finding the acceleration of the system (the main reason we use it) so important to solving physics and real world
