What is a balanced force?

Back

A balanced force occurs when two forces acting on an object are equal in size but opposite in direction, resulting in a net force of zero. The object remains still or continues to move at a constant speed.

Front

What is an unbalanced force?

Back

An unbalanced force occurs when two forces acting on an object are not equal, causing a change in the object's motion. The object will accelerate in the direction of the greater force.

Front

What is net force?

Back

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 of motion.

Front

How do you calculate net force?

Back

To calculate net force, add all the forces acting in one direction and subtract the forces acting in the opposite direction.

Front

What happens to an object when the net force is zero?

Back

When the net force is zero, the object will either remain at rest or continue to move at a constant velocity.

Front

What direction does an object move if the net force is to the right?

Back

If the net force is to the right, the object will accelerate and move to the right.

Front

What is the effect of an unbalanced force on a skateboarder going down a ramp?

Back

An unbalanced force causes the skateboarder to accelerate down the ramp, increasing their speed.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. An object at rest stays at rest, and an object in motion stays in motion unless acted upon by an unbalanced force.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object. It acts in the opposite direction to the movement and can slow down or stop the object.

Front

What is gravitational force?

Back

Gravitational force is the attraction between two objects due to their mass. It pulls objects toward each other, such as the Earth pulling objects toward its center.
