Final Review S1

Front

What is a velocity-time graph?

Back

A graph that shows the relationship between the velocity of an object and time. It can indicate acceleration and deceleration.

Front

What is a vector measurement?

Back

A measurement that has both magnitude and direction, such as velocity.

Front

How is momentum calculated?

Back

Momentum (p) is calculated using the formula p = mass (m) × velocity (v).

Front

What is the law of conservation of momentum?

Back

In a closed system, the total momentum before and after a collision remains constant.

Front

What happens to acceleration if mass is doubled while applying the same force?

Back

The acceleration is halved, according to Newton's second law (F = ma).

Front

Define momentum.

Back

Momentum is the quantity of motion an object has, dependent on its mass and velocity.

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 direction.

Front

What is Newton's second law of motion?

Back

It states that the force acting on an object is equal to the mass of that object multiplied by its acceleration (F = ma).

Front

What is the unit of momentum?

Back

The unit of momentum is kilogram meter per second (kg·m/s).

Front

What does a flat line on a velocity-time graph indicate?

Back

A flat line indicates that the object is moving at a constant velocity.
