An object at rest will remain at rest unless acted upon by an unbalanced force. Likewise, an object in motion will remain in motion unless acted upon by an unbalanced force. What is this principle called?

Back

Newton's 1st law

Front

What is force?

Back

A push or pull exerted on an object

Front

A bowling ball with a mass of 7.3 kg has a net force of 1.5 N acting on it. How large is the bowling ball's acceleration?

Back

0.21 m/s²

Front

Newton's Second Law of Motion is also known as:

Back

Law of Force and Acceleration.

Front

What is the formula for calculating force?

Back

Force = Mass × Acceleration (F = m × a)

Front

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

Back

Newton (N)

Front

What does Newton's 2nd law state?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

What is inertia?

Back

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 × Gravitational Acceleration.
