Understanding Acceleration and Velocity

The video tutorial explains the concept of acceleration using a car as an example. It distinguishes between uniform motion, where velocity remains constant, and non-uniform motion, where velocity changes. The tutorial defines acceleration as the change in velocity over time and provides a mathematical formula for calculating it.

What is the velocity of the car in the first hour in the uniform motion example?

• 80 km/h

• 110 km/h

• 90 km/h

• 100 km/h

In the uniform motion example, what is the change in velocity from the first to the second hour?

• 0 km/h

• 30 km/h

• 10 km/h

• 20 km/h

In the non-uniform motion example, what is the velocity of the car in the second hour?

• 90 km/h

• 110 km/h

• 100 km/h

• 80 km/h

In the non-uniform motion example, what is the change in velocity from the third to the fourth hour?

• 10 km/h

• -10 km/h

• 0 km/h

• 20 km/h

What term is used to describe the change in velocity over time?

• Speed

• Acceleration

• Momentum

• Force

How is acceleration mathematically defined?

• Change in direction over time

• Change in velocity over time

• Change in speed over time

• Change in distance over time

If the initial velocity is 100 km/h and the final velocity is 90 km/h over 2 hours, what is the acceleration?

• -5 km/h²

• 5 km/h²

• 10 km/h²

• -10 km/h²

What is the initial velocity referred to in the formula a = (V - U) / T?

• V

• a

• U

• T

In the context of acceleration, what does 'T' represent in the formula a = (V - U) / T?

• Distance

• Velocity

• Acceleration

• Time

What is the final velocity referred to in the formula a = (V - U) / T?

• V

• U

• T

• a
