Forces and Newton's Laws Reinforcement

Front

What is Newton's Second Law of Motion?

Back

The force acting on an object is equal to the mass of that object times its acceleration (F=ma).

Front

How do you calculate force?

Back

Force (F) is calculated using the formula F = m * a, where m is mass and a is acceleration.

Front

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

Back

The unit of force is the Newton (N).

Front

What does gravitational force refer to?

Back

Gravitational force is the force of attraction between two objects with mass.

Front

What is the formula for calculating weight?

Back

Weight (W) is calculated using the formula W = m * g, where g is the acceleration due to gravity (approximately 9.81 m/s²).

Front

What is inertia?

Back

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

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 an external force.

Front

What is the relationship between mass and acceleration in Newton's Second Law?

Back

As mass increases, for a constant force, acceleration decreases.

Front

What is Newton's Third Law of Motion?

Back

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

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.
