CP Physics A Module 04

Front

What is the net force on an object?

Back

The net force is the vector sum of all the forces acting on an object, determining its motion.

Front

What happens when forces act in opposite directions?

Back

Forces acting in opposite directions should be subtracted from each other.

Front

What is the term for the sum of all forces acting on an object?

Back

Net force.

Front

What is the relationship between net force and acceleration?

Back

The net force (Fnet) and the acceleration are always in the same direction.

Front

What occurs if acceleration and velocity are at angles to each other?

Back

The object will turn.

Front

Define 'force'.

Back

A force is a push or pull on an object resulting from its interaction with another object.

Front

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

Back

Newton (N).

Front

What is the formula for calculating net force?

Back

Net force (Fnet) = mass (m) × acceleration (a).

Front

What does it mean if the net force on an object is zero?

Back

If the net force is zero, the object is in equilibrium and will not accelerate.

Front

What is inertia?

Back

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