Physics Flashcard 3

Front

What is force in physics?

Back

Force is something that causes an object to accelerate.

Front

How do you calculate acceleration?

Back

Acceleration can be calculated by dividing the force applied (in Newtons) by the mass of the object (in kg).

Front

What is the formula for acceleration?

Back

Acceleration (a) = Force (F) / Mass (m)

Front

What does a distance-time graph represent?

Back

A distance-time graph shows how far an object has traveled over a specific period of time.

Front

How can you determine the speed of an object from a distance-time graph?

Back

Speed can be determined by calculating the slope of the line on the graph.

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 unit of force?

Back

The unit of force is the Newton (N).

Front

What is mass?

Back

Mass is a measure of the amount of matter in an object, typically measured in kilograms (kg).

Front

What is the relationship between mass and force?

Back

The greater the mass of an object, the more force is required to accelerate it.

Front

What does it mean for an object to accelerate?

Back

To accelerate means to change the velocity of an object, which can involve speeding up, slowing down, or changing direction.
