Force and Motion

Front

What is the S.I. unit for force?

Back

The S.I. unit for force is the newton.

Front

What is the term for an object's change in position relative to a reference point?

Back

The term is motion.

Front

What is a measure of the gravitational force exerted on an object?

Back

The measure is weight.

Front

How is speed defined?

Back

Speed is defined as the distance traveled divided by the time in which the motion occurred.

Front

What happens when forces are in the same direction?

Back

You add all forces together.

Front

What happens when forces are in opposite directions?

Back

You subtract the smaller force from the larger force.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity (magnitude only), while velocity is a vector quantity (magnitude and direction).

Front

What is the formula for calculating force?

Back

Force is calculated using the formula: Force = mass × acceleration (F = ma).

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object.
