Motion
The change in an object's position relative to a reference point is known as?
What is motion?
The distance an object travels per unit of time.
What is speed?
Speed in a given direction is known as?
What is velocity?
What is the difference between speed and velocity?
Velocity is speed in a direction, while speed has no direction.
A body at rest tends to remain at rest, and a body in motion tends to remain in motion, unless acted upon by an outside force.
What is Newton's First Law of Motion?
A point or object used to describe the motion of something.
What is a reference point?
What do you need to know to calculate speed and velocity?
What is distance and time?
What do you need to know to calculate the speed of an object?
What do you need to know to calculate momentum?
What is mass and velocity?
A tire at the top of a hill remains motionless, until someone pushes the tire down. Which of Newton's Laws of Motion applies to this situation?
What is Newton's First Law of Motion?
What is my house?
How do you calculate speed?
What is dividing distance traveled by time passed?
Speed = Distance / Time
Why is knowing the velocity of an approaching hurricane useful?
When an object's velocity changes, it is said to be...?
What is accelerating?
What is Newton's Third Law of Motion.
This describes how far something has traveled? It is measured in feet, miles, meters, or kilometers.
What is distance?
What are the scientific units used to measure speed?
What is meters and seconds?
How can two objects have the same speed but different velocities?
The objects are moving at the same speed in different directions.
What is the difference between distance and displacement
Distance is the total length an object has traveled, while displacement shows where the object started and ended.
A bowling ball rolls down the lane, and strikes a pin at the other end. The force of the ball hitting the pin, and the force the pin pushes back against the ball with are equal. Which of Newton's Laws would apply here?
What is Newton's Third Law of Motion?
The change in an object's position from start to finish.
Runner A and Runner B are running the 100 meter dash. Runner A finishes the race in 30 seconds, while Runner B finishes in 35 seconds. Which runner had a higher speed?
What is Runner A?
What is 35 m/s travelling south
Car A and Car B are driving down the highway at the same velocity, (31 m/s heading east). Car A has a mass of 1300 kg, while Car B has a mass of 2500 kg. Which car has the higher momentum?
Car B has a higher momentum because it's mass it higher.
The net force on a body is equal to it's acceleration multiplied by it's mass.
What is Newton's Second Law of Motion?
