Semester Review (Physics)

Front

What is the relationship between mass, acceleration, and force?

Back

According to Newton's second law of motion, force (F) is equal to mass (m) multiplied by acceleration (a): F = m * a. This means that greater mass or acceleration results in greater force.

Front

What is the effect of mass on the rate of fall of an object in a vacuum?

Back

In a vacuum, all objects fall at the same rate regardless of their mass due to the absence of air resistance.

Front

How do you calculate distance when speed and time are known?

Back

Distance can be calculated using the formula: Distance = Speed x Time.

Front

Convert 5.6 x 10^-3 to standard form.

Back

0.0056

Front

What does a steep slope on a distance-time graph indicate?

Back

A steep slope indicates a high speed, meaning the object is covering a large distance in a short amount of time.

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time.

Front

What is the principle of conservation of energy?

Back

The principle states that energy cannot be created or destroyed, only transformed from one form to another.

Front

What is kinetic energy and how is it calculated?

Back

Kinetic energy is the energy of an object in motion, calculated using the formula: KE = 1/2 mv^2, where m is mass and v is velocity.

Front

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or state, commonly calculated as PE = mgh, where m is mass, g is acceleration due to gravity, and h is height.

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.
