Unit 7 Flashcard Review Force and Motion

Front

What is the formula for calculating speed?

Back

Speed = Distance / Time

Front

How do you calculate acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time

Front

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

Back

Newton (N)

Front

What does the term 'constant speed' mean?

Back

Constant speed means moving at a steady rate without speeding up or slowing down.

Front

If a car travels 240 miles in 4 hours, what is its speed?

Back

60 mph

Front

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

Back

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

Front

What is the definition of velocity?

Back

Velocity is the speed of an object in a specific direction.

Front

What happens to the acceleration of an object if the mass increases while the force remains constant?

Back

The acceleration decreases.

Front

If a bike rider stops from a speed of 20 m/s in 4 seconds, what is the acceleration?

Back

-5 m/s²

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).
