FE Physics Extra Credit 2

Front

What is the motion of an object that is not moving?

Back

The object is at rest.

Front

What does it mean when a car has no acceleration?

Back

The car is moving at a constant speed in a straight line.

Front

What is negative acceleration?

Back

Negative acceleration means the object is slowing down.

Front

What surface has the greatest friction?

Back

Carpet has the greatest friction compared to ice, snow, and water.

Front

Why does a car accelerate when rounding a corner at constant speed?

Back

The car accelerates because its direction changes.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object.

Front

What is the formula for calculating acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is the role of friction in motion?

Back

Friction opposes the motion of an object and can cause it to slow down or stop.
