Newton's 3rd Law and Momentum

Front

What does 't' represent in the equation Ft = mΔv?

Back

Time of impact

Front

What does 'mΔv' represent in the equation Ft = mΔv?

Back

Change in momentum

Front

What happens to the average force on your body when you increase the time of impact by 10 times while jumping?

Back

About 10 times less force is experienced.

Front

How is momentum defined?

Back

Momentum is defined as mass times velocity.

Front

What does Newton's First Law state?

Back

An object in motion tends to stay in that state of motion unless acted upon by an unbalanced force.

Front

What is the formula for impulse?

Back

Impulse = Force x Time

Front

What is the relationship between impulse and momentum?

Back

Impulse is equal to the change in momentum.

Front

What does Newton's Second Law state?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

What is the formula for Newton's Second Law?

Back

F = m * a (Force = mass x acceleration)

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.
