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 motion.

Front

What happens when forces are balanced?

Back

When forces are balanced, the net force is zero, and the object will not accelerate; it will either remain at rest or continue moving at a constant velocity.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

What is motion?

Back

Motion is the change of position of an object over time, described by its distance and direction from a reference point.

Front

If you push an object with a force of 10 N and it doesn't move, what can you infer about the forces acting on it?

Back

If the object doesn't move, it means there is an equal and opposite force acting on it, making the net force zero.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object, which can occur due to a change in speed or direction.

Front

What does it mean for forces to be unbalanced?

Back

Unbalanced forces result in a net force that is not zero, causing an object to accelerate in the direction of the net force.

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 object's mass.

Front

How does mass affect the force needed to accelerate an object?

Back

The greater the mass of an object, the more force is required to achieve the same acceleration, according to Newton's second law (F=ma).
