Physics Final Review

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It is measured in meters per second squared (m/s²).

Front

How do you calculate acceleration?

Back

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

Front

What is the formula for net force?

Back

Net force (F_net) is calculated using the formula: F_net = mass (m) × acceleration (a).

Front

What is weight?

Back

Weight is the force of gravity acting on an object, calculated as weight = mass × gravitational acceleration (9.8 m/s² on Earth).

Front

What are radio waves?

Back

Radio waves are a type of electromagnetic radiation used for broadcasting signals, such as radio and television.

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or configuration, often related to height in a gravitational field.

Front

At which point in a pendulum's swing is potential energy greatest?

Back

Potential energy is greatest at the highest point of the swing (point 1).

Front

What is the relationship between mass and weight?

Back

Weight is directly proportional to mass; as mass increases, weight increases.

Front

What is the unit of force?

Back

The unit of force is the Newton (N), defined as the force required to accelerate a 1 kg mass by 1 m/s².

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity representing how fast an object moves, while velocity is a vector quantity that includes direction.
