Force Test Review

Front

What is the formula to calculate force?

Back

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

Front

What is the unit of force?

Back

Newton (N)

Front

What does Newton's 2nd Law of Motion state?

Back

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

Front

How do you calculate acceleration?

Back

Acceleration (a) = net force (F) / mass (m)

Front

What is weight?

Back

Weight is the force exerted by gravity on an object, calculated as weight (W) = mass (m) × gravitational acceleration (g).

Front

What is gravitational acceleration on Earth?

Back

Approximately 9.81 m/s².

Front

What is the relationship between mass and weight?

Back

Weight is the product of mass and gravitational acceleration.

Front

What is the net force acting on an object?

Back

The vector sum of all forces acting on the object.

Front

What does Newton's 1st 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 an example of Newton's 3rd Law of Motion?

Back

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