Forces and interactions review

Front

What is net force?

Back

The overall force acting on an object when all individual forces are combined.

Front

What is the main goal of designing a device to minimize the force on an object during a collision?

Back

To increase the time of collision.

Front

How can you measure a magnetic field?

Back

Using a compass or sensor.

Front

What happens to the force experienced when the time of a collision is increased?

Back

The force decreases.

Front

What does Newton's Law of Gravitation state?

Back

It describes the force between two objects based on their masses and the distance between them.

Front

What is the definition of acceleration?

Back

The rate of change of velocity of an object.

Front

What is impulse?

Back

The change in momentum of an object when a force is applied over a period of time.

Front

What is momentum?

Back

The product of an object's mass and its velocity.

Front

What is the relationship between mass and gravitational force?

Back

Gravitational force increases with mass.

Front

What is the effect of distance on gravitational force?

Back

Gravitational force decreases as the distance between two objects increases.
