TEKS 5A and TEKS 1

What is speed?

• Speed is the amount of time taken to travel a distance.
• Speed is the force applied to an object.
• Speed is the temperature of an object.
• Speed is the rate at which an object covers distance.

What is velocity?

• Velocity is a vector quantity that describes the speed and direction of an object's motion.
• Velocity is a scalar quantity that only measures distance.
• Velocity only refers to the speed of an object.
• Velocity is the same as speed.

What is acceleration?

• Acceleration is the speed of an object at a given moment.
• Acceleration is the force applied to an object.
• Acceleration is the distance traveled over time.
• Acceleration is change is speed or direction over time

Which of the following best describes the difference between speed and velocity?

• Neither speed nor velocity include direction.

• Both speed and velocity include direction.

• Velocity includes direction, speed does not.

• Speed includes direction, velocity does not.

If a car moves at a constant speed but changes direction, what is happening to its velocity?

• The velocity changes because direction changes.

• The speed increases.

• The car is not accelerating.

• The velocity remains the same.

What does a negative acceleration indicate about an object's motion?

• The object is speeding up.

• The object is moving at constant speed.

• The object is slowing down or changing direction.

• The object is not moving.

Which statement is true about speed and velocity?

• Velocity is always positive, but speed can be negative.

• Speed can never be greater than velocity.

• Speed is a scalar quantity, while velocity is a vector quantity.

• Velocity does not depend on direction, but speed does.
