Physics-Semester 1 Final Review

Front

What are the units for Force?

Back

N (Newtons)

Front

If the mass on an object doubles, what happens to the object's acceleration if the force remains constant?

Back

The acceleration gets cut in half (1/2).

Front

The impulse on an object is equal to what?

Back

The change in momentum of the object.

Front

What are the units for Impulse?

Back

Ns (Newton-seconds)

Front

What are the units for Velocity?

Back

m/s (meters per second)

Front

What is Newton's Second Law of Motion?

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 calculating Force?

Back

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

Front

What is momentum?

Back

Momentum is the product of an object's mass and its velocity (p = m * v).

Front

What are the units for momentum?

Back

kg·m/s (kilogram-meters per second)

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.
