The term for the change in position of an object.
What is displacement?
Projectile motion is the motion of an object through the air subject only to the acceleration of this force.
What is gravity?
This is the force that opposes the motion of two surfaces sliding past each other.
What is friction?
This is the value for the Universal Gravitational Constant, also sometimes known as "Big G".
What is
6.67xx10^-11 N⋅m^2/(kg^2)
This law states that energy can neither be created, nor destroyed.
What is the law of conservation of energy?
Displacement and velocity are examples of these types of quantities.
What are vectors?
To add vectors mathematically, one must first determine their components in these two directions.
What are vertical and horizontal?
This is the pulling force transmitted along a rope, string, or cable.
What is tension?
The direction of centripetal acceleration always acts in this direction.
What is towards the center of the circle?
This is the amount of work being done on a 3kg box that is being held above a stationary person's head.
What is zero?
If the velocity of an object changes from 10 m/s to 20 m/s in 2 seconds, it has this measurement for acceleration.
What is 5 m/s²?
The initial horizontal velocity of a projectile is found using this trigonometric function.
What is cosine (cos)?
An object is in equilibrium if the net external force acting on it is this value.
What is zero?
Without centripetal force, an object cannot follow a path of this shape.
What is a circular path?
At the highest point in its motion, an object's energy is almost entirely this type.
What is gravitational potential energy?
Acceleration can be caused by a change in what two measurements of a velocity?
What are magnitude and direction?
The distance an object falls is proportional to the square of this measurable quantity.
What is time?
If a constant, nonzero force is applied to an object, the object will have a constant value for this measurable quantity.
What is acceleration?
This force can provide centripetal force in the case of a car turning on a flat road.
What is friction?
When potential energy is converted into kinetic energy, this happens to the total energy in the system.
What is remains constant?
If an object falls for 3 seconds, it has travelled this distance. (Ignore air resistance)
What is 44.1 meters?
This is the value for acceleration due to gravity near the Earth's surface measured to 2 significant digits.
What is 9.8 m/s2?
This is the graphical representation of all external forces acting on an object. Y'all seem to hate it when I ask you to draw these.
What is a Free-Body Diagram?
This is the formula for centripetal acceleration.
What is
a_c = v^2/r ?
A machine outputs this amount of power if it does 500 J of work in 10 seconds.
What is 50 watts?
