AP Physics 1D Kinematics Review

Front

What is Kinematics?

Back

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

Front

Define speed in the context of motion.

Back

Speed is the distance traveled per unit of time, typically measured in meters per second (m/s).

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What does a speed vs. time graph represent?

Back

A speed vs. time graph shows how the speed of an object changes over time, where the slope represents acceleration.

Front

What does a distance vs. time graph represent?

Back

A distance vs. time graph shows how the distance traveled by an object changes over time, where the slope represents speed.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity per unit of time, typically measured in meters per second squared (m/s²).

Front

How does the maximum height of a projectile relate to its initial velocity?

Back

The maximum height of a projectile is proportional to the square of its initial velocity; if the initial velocity is tripled, the maximum height increases by a factor of nine.

Front

What is the formula for calculating distance when given initial velocity and acceleration?

Back

The formula is: distance = initial velocity × time + 0.5 × acceleration × time².

Front

What is the significance of the area under a velocity vs. time graph?

Back

The area under a velocity vs. time graph represents the total distance traveled by the object during that time interval.

Front

What does a horizontal line on a speed vs. time graph indicate?

Back

A horizontal line indicates constant speed, meaning the object is not accelerating.
