Force & Motion and Newton's Laws

Front

What is the effect of friction on the motion of objects?

Back

Friction slows down the motion of objects.

Front

Which force produces a change in motion?

Back

Unbalanced force produces a change in motion.

Front

Which of the following is an example of a non-contact force?

Back

Gravity is an example of a non-contact force.

Front

What is a PUSH or PULL of an object?

Back

A PUSH or PULL of an object is called Force.

Front

What does Newton's 1st Law state?

Back

An object in motion (or at rest) will stay in motion (or at rest) until an outside force acts upon it.

Front

What is Newton's 2nd Law of Motion?

Back

Newton's 2nd Law states that Force equals mass times acceleration (F=ma).

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 balanced and unbalanced forces?

Back

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

Front

What is gravitational force?

Back

Gravitational force is the attraction between two masses.

Front

What is the formula for calculating force?

Back

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