Kinematics - AP Physics REVIEW. 2024

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

What is the formula for calculating distance in uniformly accelerated motion?

Back

Distance (d) = initial velocity (u) * time (t) + 0.5 * acceleration (a) * time (t)^2.

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 is the acceleration due to gravity?

Back

The acceleration due to gravity (g) is approximately 9.81 m/s² near the surface of the Earth.

Front

How do you calculate the maximum height of an object thrown vertically?

Back

Maximum height (h) can be calculated using the formula: h = (initial velocity (v)²) / (2 * g), where g is the acceleration due to gravity.

Front

What is free fall?

Back

Free fall is the motion of an object under the influence of gravitational force only, with no air resistance.

Front

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

Back

The area under a velocity-time graph represents the displacement of the object.

Front

What is uniform motion?

Back

Uniform motion occurs when an object moves at a constant speed in a straight line.

Front

What is the formula for average velocity?

Back

Average velocity (v_avg) = total displacement / total time.

Front

What is the relationship between distance and displacement?

Back

Distance is the total path length traveled, while displacement is the straight-line distance from the initial to the final position.
