Physics Exam Review

Front

What is Newton's Second Law of Motion?

Back

Newton's Second Law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. It can be expressed with the formula: F = ma.

Front

What is the formula to calculate acceleration?

Back

Acceleration (a) can be calculated using the formula: a = (final velocity - initial velocity) / time.

Front

What is the SI unit for mass?

Back

The SI unit for mass is the kilogram (kg).

Front

What does a force of 1 Newton (N) represent?

Back

A force of 1 Newton is defined as the force required to accelerate a 1 kg mass by 1 m/s².

Front

What is the relationship between velocity and displacement?

Back

Velocity is the rate of change of displacement with respect to time. It indicates how fast an object is moving and in which direction.

Front

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

Back

The slope of a velocity vs. time graph represents acceleration.

Front

How do you calculate the distance traveled by an object?

Back

Distance can be calculated using the formula: distance = speed × 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 is the formula for calculating force?

Back

Force (F) can be calculated using the formula: F = mass × acceleration (F = ma).

Front

What is the definition of kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion, calculated using the formula: KE = 1/2 mv², where m is mass and v is velocity.
