Front

What is a force diagram?

Back

A visual representation showing the forces acting on an object, including their magnitudes and directions.

Front

What are balanced forces?

Back

Forces that are equal in size and opposite in direction, resulting in no change in motion.

Front

What are unbalanced forces?

Back

Forces that are not equal and opposite, causing a change in the motion of an object.

Front

What is net force?

Back

The overall force acting on an object, calculated by combining all individual forces acting on it.

Front

How does mass affect the motion of an object?

Back

Greater mass requires more force to change its motion compared to an object with less mass.

Front

What happens when two equal forces act in opposite directions?

Back

The object remains at rest or continues to move at a constant velocity, as the forces cancel each other out.

Front

What is inertia?

Back

The tendency of an object to resist changes in its state of motion.

Front

How does a parachute affect the motion of a toy car?

Back

A parachute increases air resistance, slowing down the car's motion.

Front

What is the relationship between force and acceleration?

Back

According to Newton's second law, force equals mass times acceleration (F=ma). More force results in greater acceleration.

Front

What is the effect of friction on motion?

Back

Friction opposes motion, slowing down or stopping moving objects.
