Kinematics
A measurement that requires both magnitude and direction.
What is a vector?
The type of motion that can have a constant velocity and a none zero constant acceleration.
What is centripetal motion?
The change in momentum when a force is applied for a time.
What is an impulse?
Examples include gravitational potential energy, elastic potential energy, and kinetic energy.
What is mechanical energy?
The rate of change of velocity.
What is acceleration?
The location where a motion is being observed.
What is a reference point?
Newton's first law, saying that an object in motion will stay in motion unless acted on by a force.
What is the law of inertia?
A collision where the objects stick together.
What is an inelastic collision?
Always equal to the change in kinetic energy.
What is Work?
A space fairing vehicle that uses recoil to travel.
What is a rocket?
The displacement after traveling 10m north and 15m south.
What is 5m south?
The time it takes for a ball thrown straight up at 12m/s to reach its highest point.
What is 1.2s?
The force when a 50kg cart slows from 20m/s to rest in 5s.
What is 200N?
The amount of kinetic energy a 2.0kg object has moving at 5m/s.
What is 25J?
The measurement of a spring that is based on the construction of the spring.
What is the spring constant?
The final velocity when a car starts from rest, and accelerates at 2.5m/s2 for 5s.
What is 12.5 m/s?
The distance a 300N/m spring is compressed by a force of 25N.
What is 0.083m?
The velocity of the second piece after an explosion of a 2kg object when a 1.5kg piece is shot 6.0m/s to the right.
What is 18m/s to the left?
The gravitational potential energy of a 2.5kg object lifted 3.0m.
What is 73.5J?
What is energy?
The distance traveled when a ball is dropped and has a final velocity of 15m/s.
What is 11.5m?
The acceleration when a 12kg box is pushed across a rough surface (coefficient of friction is 0.25) with a 90N force.
What is 5.1m/s2?
The final velocity of the 1.5 kg cart after an elastic collision in which a 0.50 kg cart moving at 4.0 m/s to the right rebounds off the first cart at 2.0 m/s.
What is 2.0m/s right?
The power output when a 500N force moves an object 2.0m in 10s.
What is 100W?
Is equal to the force of gravity when an object is sitting motionless on a table.
What is the normal Force?
