Front

What is a bar that is free to pivot about a fixed point called?

Back

Front

What is the formula for calculating acceleration?

Back

Acceleration = (Final Velocity - Initial Velocity) / Time

Front

What is the difference between speed and velocity?

Back

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

Front

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

Back

Newton (N)

Front

What is the principle of conservation of momentum?

Back

In a closed system, the total momentum before an event is equal to the total momentum after the event.

Front

What is the relationship between mass and weight?

Back

Weight = Mass × Gravitational Acceleration (W = mg)
