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

What is displacement?

Back

Displacement is the vector quantity that represents the change in position of an object, measured from the initial to the final position.

Front

What is acceleration?

Back

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

Front

What is the formula for calculating displacement when starting from rest?

Back

Displacement (s) = 0.5 * acceleration (a) * time (t)^2.

Front

What does a positive acceleration indicate?

Back

A positive acceleration indicates that an object is speeding up.

Front

What does a negative acceleration indicate?

Back

A negative acceleration (deceleration) indicates that an object is slowing down.

Front

What is the GUESS method in problem-solving?

Back

GUESS stands for Given - Unknown - Equation - Substitute - Solve, a systematic approach to solving physics problems.

Front

How do you calculate acceleration?

Back

Acceleration (a) = (final velocity (v) - initial velocity (u)) / time (t).

Front

What does the slope of a velocity vs time graph represent?

Back

The slope of a velocity vs time graph represents acceleration.

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.
