Front

What happens when two magnetic objects are placed close to each other?

Back

They can either attract or repel each other depending on the orientation of their magnetic poles.

Front

What is magnetic force?

Back

Magnetic force is the attraction or repulsion that arises between charged particles due to their motion.

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or arrangement.

Front

How does moving a magnetic cart towards a magnet affect its potential energy?

Back

Moving the cart closer to the magnet decreases its potential energy.

Front

What happens to the kinetic energy of an object when its speed increases?

Back

The kinetic energy increases as the speed of the object increases.

Front

What is kinetic energy?

Back

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

Front

What is the relationship between speed and kinetic energy?

Back

Kinetic energy is directly proportional to the square of the speed of an object.

Front

What occurs when two like magnetic poles are brought close together?

Back

They repel each other.

Front

What occurs when two opposite magnetic poles are brought close together?

Back

They attract each other.

Front

What is the formula for calculating kinetic energy?

Back

Kinetic energy (KE) = 1/2 mv², where m is mass and v is velocity.
