In 2016 there were 2025 reported collisions between trains and cars that's resulted in 265 fatalities. Explain the change in kinetic energy as it relates to conservation of momentum

How does Newton's second law of motion apply to launching rockets into space?

Does the sun have a greater gravitational force than Jupiter?

What is the positivity of electric circuits?

Forces cause changes to the motion of objects. Name a force and describe two changes it makes.

A heat engine with 0.300 mol of a monatomic ideal gas initially fills a 1000 cm3 cylinder at 500 K. The gas goes through the following closed cycle: - Isothermal expansion to 5000 cm3. - Isochoric cooling to 400 K.

The power of a machine measures A. its rate of doing work. B. its strength. C. the force it produces. D. the work it does.

the acceleration of gravity is 28 times on sun than earth. Imagine there is a space suit that let you stand on sun. Calculate the weight of 100 kg person on earth in newtons

A force of 20 n acts upon a 5 kg block, calculate acceleration of the object

What resultant force is needed to accelerate a train of mass 3.41000000 kg from rest to 15.0ms in exactly 20s
