Physics Semester Exam Review

Front

What is a balanced force?

Back

A balanced force occurs when the net force acting on an object is zero, resulting in no change in motion.

Front

What is the formula to calculate distance when given initial velocity, acceleration, and time?

Back

Distance = Initial Velocity × Time + 0.5 × Acceleration × Time²

Front

What is acceleration?

Back

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

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 does it mean when an object is in motion?

Back

An object is in motion when its position changes relative to a reference point over time.

Front

What is the unit of force in the International System of Units (SI)?

Back

The unit of force is the Newton (N).

Front

What is the relationship between mass and acceleration according to Newton's second law?

Back

According to Newton's second law, Force = Mass × Acceleration (F = ma).

Front

What is deceleration?

Back

Deceleration is a decrease in the speed of an object, which is a form of acceleration in the opposite 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 formula for calculating speed?

Back

Speed = Distance / Time.
