What is Force?

Front

What is the force of gravity acting on an object?

Back

Weight

Front

True or False: The gravitational pull of the moon is the primary cause of Earth’s ocean tides.

Back

True

Front

What is stronger, the sun’s gravitational force or that of Earth?

Back

The sun’s gravitational force is stronger.

Front

According to Newton’s second law of motion, what is the formula for force?

Back

Force = mass x acceleration

Front

True or False: The law of inertia states that an object in motion will eventually slow down and come to a complete stop if it travels far enough in the same direction.

Back

False

Front

What is inertia?

Back

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

Front

What is the relationship between mass and weight?

Back

Weight is the force exerted by gravity on an object, calculated as weight = mass x acceleration due to gravity.

Front

What does Newton's first law of motion state?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What is gravitational force?

Back

Gravitational force is the attraction between two masses, proportional to the product of their masses and inversely proportional to the square of the distance between their centers.

Front

What is the unit of force in the International System of Units (SI)?

Back

The unit of force is the Newton (N).
