Indicates how far an object ends up from its initial position, regardless of its total distance traveled.
What is displacement?
The horizontal acceleration of a projectile.
What is zero?
Always points in the same direction as acceleration.
What is net force?
All massive objects attract each other along a line connecting the two objects thanks to this force.
What is the gravitational force?
On an inclined plane, this is the equation for the component of an object's weight parallel to the incline.
What is mgsin(θ)?
A position vs. time graph's slope.
What is velocity?
The vertical acceleration of a projectile.
What is g = 10 m/s2?
An object that is at rest or traveling in a straight line at a constant speed.
What is equilibrium?
The gravitational field near the surface of the Earth has this value.
What is g = 10 m/s2 or 10 N/kg?
What is angular acceleration?
A velocity vs. time graph's slope.
What is acceleration?
Use this to determine the magnitude of a vector when given two components.
What is the Pythagorean Theorem?
A bathroom scale reads this force.
What is the normal force?
How much an object's angular velocity changes per second.
What is angular acceleration?
The equation for the rotational inertia for a point particle.
What is I = mr2?
Tells how much an object’s speed changes in one second.
What is acceleration?
Use this to determine the direction of a vector given two components.
What is the inverse of tangent?
The force of the Earth on a book, and the force of the book on the Earth are examples of this.
What is an action-reaction force pair?
The equation that converts between angular velocity and linear velocity.
What is v = rω?
This angle between the force and lever arm provides a maximum torque.
What is 90˚?
The area under the curve of a velocity vs. time graph.
What is displacement?
Both acceleration and vertical velocity of a falling projectile have this sign.
What is negative?
The number that tells how sticky two surfaces are.
What is the coefficient of friction?
Measured in radians, this quantity indicates the angle through which an object has rotated.
What is angular displacement?
Friction, gravity, normal, and tension forces are all examples of this type of inward net force.
