|
The motion energy of an object depends on the speed and mass of the object.

EG092002
|
The motion energy of an object depends on the speed of the object but not the direction the object is moving.

RG082002
|
Kinetic energy is proportional to the speed squared, so when a moving object has its speed decreased by half the kinetic energy of that object decreased by one fourth.

EG001007
|
For two balls that have the same mass, the ball that is rolling faster has more motion energy.

|
RG174001
|
Kinetic energy is proportional to mass, so when a moving object has its mass increased by two the kinetic energy of that object increases by two. (Item uses bar graphs.)

RG062003
|
When comparing two airplanes thrown at different speeds, the faster plane has more energy because it has a higher speed.

EG025002
|
In order to know which of two objects is moving faster, you need to know the weight (mass) of each object in addition to the motion energy.

For two balls that have the same mass, the ball that is rolling faster has more motion energy.

|
RG060003
|
When comparing the a ball dropped down and a ball thrown down, the thrown ball has more energy because it is moving faster.

EG080002
|
When comparing two bike riders with different amounts of motion energy, the only way to know which one is riding faster is to also know the weight (mass) of each.
