Each student exerts a force on the other but “B” exerts the larger force.
Each student exerts the same amount of force on each other.
A semi truck (high mass) and smart car (small mass) are traveling in different directions at the same high speed, there is a head on collision, which answer best describes the result.
The semi truck will move backwards due to the greater force of the smart car
There will be no damage to either vehicle
The smart car will be sent in the direction of the semi trucks motion due the greater force of the semi truck
Nothing would occur

In the diagram below a pitcher is throwing a ball with the same mass, if scenario B has more kinetic energy than scenario A what must be true?
The pitcher threw the ball faster in scenario A
The pitcher threw the ball faster in scenario B
The pitcher threw the ball at the same speed in both scenarios
The kinetic energy is not affected by speed or mass.
Using the graphs above, what best describes the relationship between KE, mass, and velocity?
Mass has an exponential relationship with KE, while velocity has a linear relationship
The more KE and object has, the less velocity it will have
Mass has an linear relationship with KE, while velocity has a exponential relationship
If an object has a low mass and a low velocity, the KE will be high
