Newton's laws

Front

What is the definition of density?

Back

Density is the mass per unit of volume of a substance.

Front

What does Newton's second law state?

Back

Newton's second law states that the acceleration of an object is equal to the net force acting on the object divided by the object's mass.

Front

What is the force exerted by a baseball on a bat if the bat hits the baseball with a force of 100 Newtons?

Back

The force exerted by the baseball on the bat is 100 Newtons in the opposite direction.

Front

What happens when you apply a force on an object according to Newton's third law?

Back

When you apply a force on an object, the object applies an equal and opposite force.

Front

What is an object's weight proportional to?

Back

An object's weight is proportional to its mass.

Front

What is Newton's first law of motion?

Back

Newton's first law states that an object at rest will remain at rest, and an object in motion will remain in motion at a constant velocity unless acted upon by a net external force.

Front

What is the formula for calculating force?

Back

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

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's mass.

Front

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

Back

The unit of force in SI is the Newton (N).
