Force & Net Force

Front

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 no change in motion.

Front

What is an unbalanced force?

Back

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

Front

What is net force?

Back

Net force is the overall force acting on an object after all the individual forces are combined.

Front

If the net force on an object is 0N, what does that indicate about the object's motion?

Back

It indicates that the object is either at rest or moving at a constant speed.

Front

What happens to an object at rest when balanced forces act on it?

Back

The object remains at rest.

Front

What happens to an object in motion when balanced forces act on it?

Back

The object continues to move at a constant speed in a straight line.

Front

In a tug-of-war, if one group pulls with a greater force, what happens to the ribbon in the middle?

Back

The ribbon will move towards the group that is pulling with the greater force.

Front

What is kinetic energy?

Back

Kinetic energy is the energy an object possesses due to its motion.

Front

At which point does a roller coaster car have the greatest kinetic energy?

Back

The car has the greatest kinetic energy at the lowest point of the track.

Front

What is the effect of friction on motion?

Back

Friction opposes the motion of an object, causing it to slow down or stop.
