Kinematics

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.

What is the formula for calculating final velocity when an object is dropped from a height?

Back

Final velocity (v) can be calculated using the formula: v = √(2gh), where g is the acceleration due to gravity (approximately 9.81 m/s²) and h is the height from which the object is dropped.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object with respect to time.

Front

What does a flat line on a distance-time graph indicate?

Back

A flat line on a distance-time graph indicates that the object is not moving.

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 kinematic equation for uniformly accelerated motion?

Back

The kinematic equations relate displacement, initial velocity, final velocity, acceleration, and time. One common equation is: s = ut + 1/2 at², where s is displacement, u is initial velocity, a is acceleration, and t is time.

Front

What is the significance of the acceleration due to gravity?

Back

The acceleration due to gravity (approximately 9.81 m/s²) is the rate at which an object accelerates towards the Earth when in free fall.

Front

What does it mean if an object has a negative acceleration?

Back

Negative acceleration indicates that the object is slowing down or decelerating.

Front

What is displacement?

Back

Displacement is the shortest distance from the initial to the final position of an object, taking direction into account.

Front

What is the relationship between distance and displacement?

Back

Distance is the total path length traveled by an object, while displacement is the straight-line distance between the starting and ending points.
