AS Physics

Front

vector quantity

Back

A quantity with magnitude and direction.

Front

precision

Back

Precision is determined by the range in the measurements/values/readings/data/results.

Front

acceleration

Back

Rate of change of velocity

Front

What is velocity?

Back

Change in displacement / time.

Front

What is momentum?

Back

Product of mass and velocity.

Front

State the principle of conservation of momentum.

Back

The sum/total momentum of a system of bodies is constant.

Front

What is the center of gravity of an object?

Back

Point where the weight is taken to act.

Front

Define force in terms of momentum.

Back

Rate of change of momentum.

Front

State Newton's 1st Law.

Back

A body/mass/object continues (at rest or) at constant/uniform velocity unless acted on by a resultant force.

Front

State Newton's 2nd Law.

Back

Resultant force is proportional/equal to the rate of change of momentum.
