How does the weight of a rocket affect the height and distance?

Define, identify, and differentiate different forms of energy

Which type of wave cannot transmit energy through a vacuum

While goofing off at the ice skating rink, a student takes off her shoes and places each of them on the ice. Her friend, a hockey player, then shoots a hockey puck at each shoe.

For long-distance transmission of power, in order to reduce losses in the wires by driving a low current at high voltage, we should a) use a step-up transformer b) change the length of the wires between transmission towers c) not use a transformer

In a gas kept at a constant temperature, all molecules move with the same speed.

Describe and apply Newton's Three Laws

If you do 1000j of work on a system and remove 500j of heat from it, what is the change in its internal energy

Two children stretch a jump rope between them and send wave pulses back and forth on it. The rope is 4.5 m long, its mass is 0.42 kg, and the force exerted on it by the children is 71 N.

An object will only change its motion if a force is directly applied to it. is this a true statement?

Janice has just measured the density of an object. Which value is possible? (Density: D = )
