Speed, Velocity, and Acceleration Vocabulary

What is displacement?

• A scalar quantity that refers to the total distance traveled by an object.

• A vector quantity that refers to the change in position of an object, including direction.

• The distance between two points without considering direction.

• A measure of how far an object has moved from its original position, ignoring direction.

What is acceleration?

• The rate at which an object changes its velocity.

• The force applied to an object to move it.

• The distance covered by an object in a given time.

• The speed of an object in a straight line.

What is a vector quantity?

• A physical quantity that has only magnitude.

• A physical quantity that has both magnitude and direction, such as velocity and acceleration.

• A quantity that can be represented by a single number.

• A measurement that does not depend on direction.

What does it mean for an object to be in uniform motion?

• An object is in uniform motion when it moves at a constant speed in a straight line.

• An object is in uniform motion when it changes speed continuously.

• An object is in uniform motion when it moves in a circular path.

• An object is in uniform motion when it is at rest.

What is deceleration?

• A type of acceleration that occurs when an object speeds up.

• A type of acceleration that occurs when an object slows down.

• A measure of the distance traveled by an object.

• A force that acts on an object in motion.

What is velocity?

• Velocity is the speed of an object in a specific direction.

• Velocity is the total distance traveled by an object.

• Velocity is the rate of change of an object's mass.

• Velocity is the speed of an object regardless of direction.

What is speed?

• Speed is the distance traveled by an object in a given amount of time, usually expressed in units like meters per second (m/s) or kilometers per hour (km/h).

• Speed is the rate at which an object accelerates over time.

• Speed is the total distance covered by an object regardless of time.

• Speed is the measure of how quickly an object changes its position.

What is a scalar quantity?

• A physical quantity that has both magnitude and direction, such as velocity.

• A physical quantity that has only magnitude and no direction, such as speed and distance.

• A quantity that can be represented by a vector in a coordinate system.

• A measurement that is always constant and does not change over time.

What is the difference between speed and velocity?

• Speed is a scalar quantity that measures how fast an object is moving, while velocity is a vector quantity that measures speed in a specific direction.

• Speed and velocity are the same; both measure how fast an object is moving.

• Speed is a vector quantity that measures speed in a specific direction, while velocity is a scalar quantity that only measures how fast an object is moving.

• Speed is the rate of distance covered, while velocity is the rate of change of position.
