A Position describes the location of an object.
What is true
100
If an object has low acceleration, it isn't moving very fast.
False
100
A force can act directly on an object?
What is true?
100
Earth's gravity makes heavy objects fall faster than light objects.
What is False
100
True or False: Depth affects fluid pressure.
What is True
200
This is a change in a position over time.
What is Motion
200
The rate at which velocity changes.
What is acceleration?
200
A simple push or pull.
What is force?
200
Something is in this when gravity is pulling it down and no other forces are acting on it.
What is free fall
200
An upward force that fluids exert on all matter.
What is Buoyant Force
300
This is a way to calculate the speed of an object that may not always be moving at a constant speed.
What is Average Speed
300
Acceleration in a circular motion.
What is centripetal acceleration
300
The tendency of all objects to resist a change in motion
What is Inertia?
300
A force of attraction between objects due to their mass.
What is gravity?
300
The SI unit for pressure
What is pascal?
400
How are distance, time, and speed related.
You need to find out distance and time to find speed
400
An object that starts off moving at 8 meters per second west, and then 16s later is moving 48 meters per second west. What is the average acceleration.
What is 2.5 meters per second^2
400
When forces of 1 N and 2 N act in the same direction on an object the net force is what?
What is 3 N
400
On earth, gravity is about how many meters per second squared?
What is 9.8 m/s^2
400
Calculate the pressure that water exerts on the bottom of an aquarium tank. The water presses down on the bottom with a force of 2,000 N, and the area of the bottom of the tank is 0.04 m^2
What is 5,000 Pa
500
This runner completed a 100-meter with a time of 13.75 seconds. What was her average speed?
What is 7.3 meters per second
500
How does motion change?
Objects change direction and speed when accelerating.
500
How does forces affect motion?
A force can change motion by affecting it's motion.
500
What determines the force of gravity?
Distance and Mass
500
What can happen as a result of weight and buoyant force?
Some objects float, Some objects sink, and some objects are Buoyed up.
