Kinematics Review

Front

What is the unit of acceleration?

Back

m/s²

Front

When is the equation best used when ____ is NOT given?

Back

time

Front

An object travels from rest and accelerates at 5.21 m/s² for 10 seconds. What is the object’s displacement? Which equation should be used?

Back

Use the equation: displacement = initial velocity * time + 0.5 * acceleration * time²

Front

What does the GUESS method stand for?

Back

Given - Unknown - Equation - Substitute - Solve

Front

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

Back

acceleration

Front

Define displacement in kinematics.

Back

Displacement is the change in position of an object, measured as a straight line from the initial to the final position.

Front

What is the difference between speed and velocity?

Back

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

Front

What is the formula for calculating average speed?

Back

Average speed = total distance / total time.

Front

What is the significance of a negative acceleration?

Back

Negative acceleration indicates that an object is slowing down.

Front

What is the formula for calculating acceleration?

Back

Acceleration = (final velocity - initial velocity) / time.
