Motion and speed
An elevator traveled 150 feet at a speed of 4.5m/s. What information do we need to determine the velocity of the elevator?
What is direction?
The rate at which velocity changes.
What is acceleration?
A push or a pull.
What is force?
The force between objects due to their mass.
What is gravity?
Any material that can flow and take the shape of its container.
What is a fluid?
In a race Miho swam the first 50 m in 42 s. She swam the second 50 m in 40 s. What was her average speed for the race?
What is 1.22 m/s?
Moving from a small velocity to a large velocity.
What is positive acceleration?
The combination of all forces acting on an object.
What is net force?
Gravity is pulling down and no other forces are acting on the object.
What is free fall?
How much force in a given area.
What is pressure?
The location of an object.
What is position?
Moving from a high velocity to a low velocity.
What is negative acceleration?
An objects tendency to resist a change in motion.
What is Newtons First Law of Motion?
When an object moves around another object in space.
What is orbit?
The SI unit for pressure.
What is the pascal?
Juan lives 100 m away from Bill. What is Juan's average speed if he reaches Bill's house in 50 seconds?
What is 2 m/s?
Acceleration in a circular motion.
What is centripetal acceleration?
The acceleration of an object depends on the mass of the object and the amount of force applied.
What is Newton's 2nd law of Motion?
What is the gravitational force acting on an object that has a mass of 100 kg?
What is 980 kg m/s2?
The weight of the atmosphere.
What is atmospheric pressure?
How would decreasing the time it takes you to run a certain distance affect your speed?
What is you would increase your speed?
What is the acceleration experienced by a car that takes 10 s to reach 27 m/s from rest?
What is 2.7 m/s2?
Whenever one object applies force on a second object, the second object exerts an equal and opposite force on the first.
What is Newton's 3rd law of Motion?
What two motions combine to produce an orbit?
What is forward and downward motion?
The pressure a fluid exerts on the bottom of an object.
What is buoyant force?
