ICP 4 Net Force Practice

Front

What is net force?

Back

Net force is the vector sum of all forces acting on an object. It determines the object's acceleration.

Front

What happens to net force when two forces act in the same direction?

Back

When two forces act in the same direction, you add the forces together to find the net force.

Front

What happens to net force when two forces act in opposite directions?

Back

When two forces act in opposite directions, you subtract the smaller force from the larger force to find the net force.

Front

What is kinetic friction?

Back

Kinetic friction is the frictional force that opposes the motion of an object that is sliding over a surface.

Front

What is static friction?

Back

Static friction is the frictional force that prevents an object from starting to move when a force is applied.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

What is the relationship between net force and acceleration?

Back

According to Newton's second law, the net force acting on an object is equal to the mass of the object multiplied by its acceleration (F = ma).

Front

What is balanced force?

Back

Balanced forces are two or more forces acting on an object that are equal in size and opposite in direction, resulting in no change in motion.

Front

What is an unbalanced force?

Back

An unbalanced force occurs when the total forces acting on an object are not equal, causing the object to accelerate in the direction of the net force.

Front

What is the formula to calculate net force?

Back

Net force (F_net) = F1 + F2 + ... + Fn, where F1, F2, ..., Fn are the individual forces acting on the object.
