Forces and Newton's First Law

Front

What is net force?

Back

The net force is the overall force acting on an object when all the individual forces are combined. It determines the object's acceleration and direction.

Front

What unit is used to measure force?

Back

The unit used to measure force is the newton (N).

Front

Objects with greater _________ also have greater inertia.

Back

mass

Front

What happens when two teams pull with the same amount of force?

Back

They will not move at all.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. It is directly related to the mass of the object.

Front

What is the formula for calculating force?

Back

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

Front

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

Back

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

Front

What does it mean if an object is in equilibrium?

Back

An object is in equilibrium when the net force acting on it is zero, resulting in no acceleration.

Front

What is the effect of friction on motion?

Back

Friction opposes the motion of an object, acting in the opposite direction to the applied force.

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces result in no change in motion, while unbalanced forces cause an object to accelerate.
