I WONDER - What Is Acceleration?

The video tutorial explains the concepts of speed, velocity, and acceleration. Speed is how fast an object moves, while velocity includes direction. Acceleration is the rate of change of velocity. The tutorial provides an example of calculating acceleration when a car speeds up and explains the difference between positive acceleration and deceleration.

What does speed measure?

• The direction of an object's movement

• How fast an object is moving

• The rate of change of velocity

• The distance covered by an object

How is velocity different from speed?

• Velocity includes direction, while speed does not

• Velocity is always greater than speed

• Velocity measures distance, speed measures time

• Velocity is a scalar quantity, speed is a vector

What is acceleration?

• The distance an object travels over time

• The direction of an object's movement

• The speed of an object

• The rate at which an object changes its velocity

If a car goes from 0 to 60 mph in 5 seconds, what is being calculated?

• Speed

• Velocity

• Acceleration

• Distance

What is deceleration?

• Change in direction

• Negative acceleration

• Positive acceleration

• Constant speed
