Physics Final Exam Review

Front

What is the correct unit for measuring velocity in physics?

Back

m/s

Front

How do you calculate the distance traveled by an object under constant deceleration?

Back

Use the formula: \(d = \frac{{v^2}}{{2a}}\), where \(d\) is distance, \(v\) is initial velocity, and \(a\) is acceleration.

Front

What is the relationship between force and mass in a collision?

Back

According to Newton's Third Law, the force on the bug and the force on the car are the same.

Front

What does it mean when no net force is applied to an object?

Back

It means the object is either at rest or moving at a constant velocity.

Front

How do you calculate the final velocity of an object under constant acceleration?

Back

Use the formula: \(v = u + at\), where \(v\) is final velocity, \(u\) is initial velocity, \(a\) is acceleration, and \(t\) is time.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity per unit time, measured in m/s².

Front

What is the formula for calculating force?

Back

Force is calculated using the formula: \(F = ma\), where \(F\) is force, \(m\) is mass, and \(a\) is 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.

Front

What is the principle of conservation of momentum?

Back

In a closed system, the total momentum before an event is equal to the total momentum after the event.

Front

What is deceleration?

Back

Deceleration is a decrease in speed or negative acceleration, measured in m/s².
