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 velocity in the context of Kinematics.

Back

Velocity is the rate of change of displacement with respect to time, and it is a vector quantity, meaning it has both magnitude and direction.

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 does the integral of velocity represent?

Back

The integral of velocity over time represents the total displacement of an object during that time interval.

Front

How do you find the acceleration from a velocity function?

Back

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

Front

What is the relationship between position, velocity, and acceleration?

Back

Position is the integral of velocity, and velocity is the integral of acceleration.

Front

What is the formula for average velocity?

Back

Average velocity is calculated as the total displacement divided by the total time taken.

Front

What is the significance of a negative velocity?

Back

A negative velocity indicates that the object is moving in the opposite direction to the defined positive direction.

Front

How can you determine when a particle's speed is increasing?

Back

A particle's speed is increasing when its acceleration and velocity have the same sign (both positive or both negative).

Front

What does it mean if the acceleration is zero?

Back

If the acceleration is zero, the object is moving at a constant velocity.
