In a longitudinal wave, the energy and the source move in this direction relative to each other
What is parallel?
400
To make an object move in a circle, the force must point in this direction
What is towards the center?
400
A roller coaster car weighs 5000 N when loaded with people. It has this much potential energy when it is at the top of a 30 m high hill.

Asha is making candles. She uses a thermometer to measure the temperature of the wax as she heats it. At first the temperature increases steadily, but then the temperature stops changing because of this.
What is the wax begins to melt/undergo a phase change?
400
A negative charged metal sphere is grounded. The electrons move in this direction.
What is "the electrons move from the sphere to the ground"?
400
When a fire truck moves away from you, the siren sounds this way (compared to if it were at rest)
What is lower pitch/frequency?
500
In a laboratory experiment on friction, a block resting on a rough table is pulled by a horizontal wire. The pull gradually increases until the block begins to move and then a force is applied so that the block moves at a constant speed. The force of kinetic friction acting on the block is this value.
What is 15 N?
500
A 30,000 kg train car moving at 8 m/s collides with a 30,000 kg car at rest.
The combined cars move with this much momentum.
What is 240,000 kg m/s?
500
Malik is heating water to make tea. He heats 100 g of water from 22°C to 100°C. This is the amount of heat needed.
