Physics Skills
This term describes how well the results of a measurement agree with the "real" or accepted value.
What is Accuracy?
This is calculated by dividing the total distance covered by the total travel time.
What is Average Speed?
This type of quantity has magnitude (size) but no direction.
What is Scalar?
This law, also known as the Law of Inertia, states that an object at rest will stay at rest unless acted upon by an unbalanced force.
What is Newton's First Law?
On a velocity vs. time graph, a horizontal line (zero slope) indicates that the object is moving with this type of velocity.
According to the rules, this is the number of significant figures in the value 0.0032.
What is 2?
When air resistance is negligible, all falling objects on Earth accelerate at approximately this rate.
What is 9.8 m/s/s?
If one bullet is fired horizontally and another is dropped from the same height at the exact same time, this is when they will hit the ground.
What is at the same time?
This contact force acts perpendicular to the surface of contact and is what you "feel" when standing on a floor.
What is Normal Force?
This is the degree of exactness in a measurement, often indicated by the number of significant figures used.
What is precision?
This type of relationship is represented by the equation y = mx + b.
What is a Linear Relationship?
Jermaine runs exactly two laps around a 400m track; this is his total displacement.
What is 0?
If Peter walks 100 ft north and 250 ft west, this is his calculated total displacement magnitude.
What is 269.3 ft?
This type of friction exists between surfaces that are sliding past each other.
This type of friction exists between surfaces that are sliding past each other.
Acceleration is defined as the rate at which ________ changes over time.
What is Velocity?
Convert 12,345 mm into km.
What is 0.012 km?
Starting from rest, a car accelerates at 4.2 m/s² for 5 seconds; this is its final velocity.
What is 21 m/s?
Homer is tossed horizontally off a 40m cliff at 25 m/s; he will land this far from the base of the cliff.
What is 71.5 meters?
An object is moving at a constant velocity. If the mass of the object is 34 kg and the coefficient of kinetic friction is 0.2, this is the force of friction.
What is 66.64 N?
These two components of projectile motion are independent of one another but occur simultaneously.
What are horizontal and vertical components?

What is 4.05 ft?
A plane starts from rest and accelerates down a runway at 4m/s/s for 10 seconds before lifting off. How many meters of runway did it use?
What is 200 meters?
An explorer starts at a base camp and treks 400 meters Due East to collect samples. They then turn and hike 300 meters Due North to reach a lookout point. What is the explorer’s total displacement (both magnitude and direction)?
What is 500 meters @ 36.9 degrees N of E?
A rock is thrown horizontally off a 20 m high cliff with a horizontal velocity of 10 m/s. How far from the base of the cliff does it land?
What is 20 m?
