Find the acceleration of a forklift of mass 1400 kg pushed by a force of 2100 N that is opposed by friction force of 425 N

Why is a standard system of measurement important? a.) scientists want to share measurment data they can understand B) each country wants it's own set of measurements standards C.) measurements are seldom shared with scientists.

As soon as parachute of a falling soldier opens, how will the accleration change?

What is the relationship between thermal energy and friction

A satellite orbiting above the earth needs no power source to keep orbiting the earth. The best explanation for this involves the law of inertia.

Which statement is true about an object that is moving in a circular motion due to centripetal force, F, when the radius of its circular motion is doubled?

What is one way to increase the amplitude of a wave in a medium

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
