Unit 1 PS: Forces & Motion

Front

What is the definition of active listening?

Back

Active listening is a communication technique that involves fully concentrating, understanding, responding, and remembering what is being said.

Front

What is the standard unit of measurement for velocity?

Back

Meters per second (m/s) is the standard unit of measurement for velocity.

Front

True or False: On Earth, the velocity of a falling object changes by 10 meters per second each second.

Back

True.

Front

How do you calculate acceleration?

Back

Acceleration is calculated by the formula: a = (final velocity - initial velocity) / time.

Front

What is the formula for calculating time when given acceleration and change in velocity?

Back

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

Front

What does 'magnitude' refer to in physics?

Back

Magnitude refers to the greatness of size, strength, or importance of a quantity.

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 velocity?

Back

Velocity is calculated using the formula: velocity = distance / time.

Front

What is the unit of acceleration?

Back

The unit of acceleration is meters per second squared (m/s²).

Front

What is the effect of gravity on falling objects?

Back

Gravity causes falling objects to accelerate towards the Earth at approximately 9.81 m/s².
