Kinematics - Vocabulary

Front

What is displacement?

Back

Displacement is the shortest distance from the initial to the final position of an object, along with the direction.

Front

What is kinematics?

Back

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

Front

What does negative acceleration mean?

Back

Negative acceleration means that an object is slowing down or changing its motion toward the negative direction.

Front

Is negative speed possible?

Back

Negative speed is impossible; speed is a scalar quantity and cannot be negative.

Front

What are the units of measurement for acceleration?

Back

The units of measurement for acceleration are meters per second squared (m/sec²).

Front

What is velocity?

Back

Velocity is the rate of change of displacement and includes both speed and direction.

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 uniform motion?

Back

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

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) is calculated using the formula: a = (final velocity - initial velocity) / time.

Front

What is the significance of a positive acceleration?

Back

Positive acceleration indicates that an object is speeding up in the direction of its motion.
