Unit 7 Motion and force

Front

What is Newton's First Law of Motion?

Back

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 an external force.

Front

What is the definition of net force?

Back

The net force is the vector sum of all the forces acting on an object.

Front

How do you calculate acceleration?

Back

Acceleration is calculated by the formula: a = (final velocity - initial velocity) / time.

Front

What is a balanced force?

Back

Balanced forces are forces that have a net force of zero Newtons, resulting in no change in motion.

What is a reference point in motion?

Back

A reference point is an object that appears to stay in place and is used to determine the position of another object.

Front

What is Newton's Second Law of Motion?

Back

Newton's Second Law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass (F = ma).

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

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.

Front

What is inertia?

Back

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

What is the formula for calculating force?

Back

The formula for calculating force is F = ma, where F is force, m is mass, and a is acceleration.
