Forces and Motion

Front

What is the formula to calculate force?

Back

Force = mass x acceleration

Front

What is net force?

Back

The overall force acting on an object when all the individual forces are combined.

Front

What accounts for the difference in gravity between Earth and the Moon?

Back

Mass.

Front

In a tug of war, if the left team pulls with 200N and the right team with 150N, what is the net force?

Back

50N to the left.

Front

What type of forces cause a change in an object's motion?

Back

Unbalanced forces.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

What is the unit of force?

Back

Newton (N).

Front

What is acceleration?

Back

The rate of change of velocity of an object.

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces do not change an object's motion; unbalanced forces do.

Front

What is gravitational force?

Back

The force of attraction between two masses.
