TermDefinition
Free Fall An object in free fall is considered to have no appreciable air resistance active on it. All objects in free fall experience the same acceleration due to gravity. Near the surface of the Earth that acceleration is g=9.8 m/s^2.
Gravitational Field Strength (g) The magnitude of the strength of a gravitational field at any point is the force per unit mass at that point in the gravitational field; also referee to as the acceleration die to gravity: g=F/m
Head to Tail A method of vector addition and subtraction whereby two or more vectors, drawn to a scale, are placed in a line, head to tail. The tail of the second vector drawn from the head of the first vector.
Horizontal Displacement A vector quantity that represents the horizontal length and direction of a straight line path of motion of an object from it's starting point to its finishing point.
Projectile Motion The motion of an object projected by a force and continuing in a path produced by the action of the projecting force and gravity
Resultant A single vector that produces the same effect as the combination of two or more concurrent vectors.
Scalar Quantity A quantity having only magnitude. Unlike a vector quantity, no direction is implied in a scalar.
Vector A quantity defined by magnitude and direction. For example force, acceleration. Velocity, and displacement are all vector quantities.
Vector Components A single vector may be resolved into an unlimited number of components such that the sum of the components is equal to the original vector.
Vertical Displacement A vector quantity that represents the vertical length and direction of a straight line path of motion of an object from its starting point to its finishing point.
Horizontal Component Any vector can be resolved into any number of components. Usually we resolve a vector into two components perpendicular to each other, one on the x-axis, one on the y-axis. Horizontal component of a vector quantity represents projection on the x-axis
Projectile AN object that is projected into motion by an external force and continuing in motion by its own inertia.

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

• SPACEBAR - flip the current card
• LEFT ARROW - move card to the Don't know pile
• RIGHT ARROW - move card to Know pile
• BACKSPACE - undo the previous action

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
