Chapter 1 & 2 Vocab

What is the definition of speed?

• The rate of change of position in which the same distance is traveled each second.

• The distance an object moves divided by the time it takes to move that distance.

• An object’s speed at a specific instant in time.

• The total distance traveled divided by the total time taken to travel that distance.

What is the definition of velocity?

• The rate of change of position in which the same distance is traveled each second.

• The distance an object moves divided by the time it takes to move that distance.

• The speed and the direction of a moving object.

• A measure of the change in velocity during a period of time.

What is the definition of force?

• A push or pull on an object.

• An attractive force that exists between all objects that have mass.

• The amount of matter in an object.

• The gravitational force exerted on an object.

What is the definition of inertia?

• The tendency of an object to resist a change in its motion.

• The rate of change of position in which the same distance is traveled each second.

• A measure of the change in velocity during a period of time.

• The speed and the direction of a moving object.

What is the definition of momentum?

• A measure of how hard it is to stop a moving object.

• The total momentum of a group of objects stays the same unless outside forces act on the objects.

• In circular motion, a force that acts perpendicular to the direction of motion, toward the center of the curve.

• The gravitational force exerted on an object.

What is the definition of friction?

• A contact force that resists the sliding motion of two surfaces that are touching.

• The rate of change of position in which the same distance is traveled each second.

• A measure of the change in velocity during a period of time.

• The speed and the direction of a moving object.
