Impulse and Conservation of Momentum Flashcard

Front

What is momentum?

Back

Momentum is defined as mass in motion. It is the product of an object's mass and its velocity.

Front

What does a graph showing constant speed look like?

Back

A graph showing constant speed is a straight line with a positive slope, indicating that distance increases uniformly over time.

Front

What is impulse?

Back

Impulse is the change in momentum of an object when a force is applied over a period of time. It is calculated as the product of force and the time duration over which the force acts.

Front

How is impulse related to momentum?

Back

Impulse is equal to the change in momentum of an object. Mathematically, Impulse = Change in Momentum = Final Momentum - Initial Momentum.

Front

What is the formula for calculating impulse?

Back

Impulse (J) = Force (F) × Time (t).

Front

If a 25 kg bike changes its velocity by 7 m/s, what is the impulse?

Back

Impulse = mass × change in velocity = 25 kg × 7 m/s = 175 N*s.

Front

How do you calculate force from impulse?

Back

Force can be calculated using the formula: Force (F) = Impulse (J) / Time (t).

Front

What is the unit of impulse?

Back

The unit of impulse is Newton-seconds (N*s).

Front

What does a graph with a horizontal line represent?

Back

A horizontal line on a distance-time graph represents an object that is not moving.

Front

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

Back

According to Newton's second law, Force (F) = Mass (m) × Acceleration (a).
