Kinematics

Front

What is Kinematics?

Back

Kinematics is the branch of mechanics that describes the motion of objects without considering the forces that cause the motion.

Front

Define displacement.

Back

Displacement is the vector quantity that represents the change in position of an object, measured from the initial to the final position.

Front

What is the difference between distance and displacement?

Back

Distance is a scalar quantity that measures the total path length traveled, while displacement is a vector quantity that measures the shortest straight-line distance from the initial to the final position.

Front

What is velocity?

Back

Velocity is the rate of change of displacement with respect to time, and it is a vector quantity.

Front

How is average velocity calculated?

Back

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity with respect to time, and it can be positive (speeding up) or negative (slowing down).

Front

What is the formula for calculating acceleration?

Back

Front

What does it mean when velocity is positive and acceleration is negative?

Back

When velocity is positive and acceleration is negative, the object is slowing down.

Front

What is the significance of the slope of a position-time graph?

Back

The slope of a position-time graph represents the velocity of the object.

Front

How do you find the velocity function from a position function?

Back

The velocity function is found by taking the derivative of the position function with respect to time.
