Newtons Laws of Motion

Front

What is the attractive force that exists between all objects that have mass?

Back

Gravity is the force that attracts two bodies towards each other, depending on their masses and the distance between them.

Front

At which point is potential energy greatest?

Back

Potential energy is greatest at the highest point in a system, such as point W in a gravitational field.

Front

If one object has twice as much mass as another object, what else does it have twice as much of?

Back

Inertia. An object with greater mass has greater inertia, meaning it resists changes in its state of motion.

Front

What type of force produces a change in motion?

Back

An unbalanced force is required to change the motion of an object, as it overcomes inertia.

Front

What does Newton's 3rd Law of Motion state?

Back

For every action, there is an equal and opposite reaction.

Front

What is mass?

Back

Mass is a measure of the amount of matter in an object, typically measured in kilograms.

Front

What is weight?

Back

Weight is the force exerted by gravity on an object, calculated as mass times the acceleration due to gravity (W = mg).

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion; it depends on the object's mass.

Front

What is the difference between balanced and unbalanced forces?

Back

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

Front

What is gravitational acceleration?

Back

Gravitational acceleration is the acceleration of an object due to the force of gravity, approximately 9.81 m/s² on Earth.
