What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It can involve changes in speed or direction.

Front

What is plate tectonics?

Back

Plate tectonics is the theory that Earth's surface is divided into crustal plates that move due to convection currents in the mantle.

Front

What causes an object to move?

Back

An object will move when unbalanced forces are applied to it.

Front

What is kinetic energy?

Back

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

Front

What is potential energy?

Back

Potential energy is the stored energy of an object due to its position or state.

Front

How does energy transform in a roller coaster?

Back

As a roller coaster moves, it transforms kinetic energy to potential energy and vice versa, depending on its height.

Front

What is an unbalanced force?

Back

An unbalanced force is a force that causes an object to accelerate, changing its state of motion.

Front

What is the relationship between mass and acceleration?

Back

According to Newton's second law, acceleration is inversely proportional to mass when the same force is applied.

Front

What happens when balanced forces act on an object?

Back

When balanced forces act on an object, it remains at rest or continues to move at a constant speed.

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) can be calculated using the formula: a = (final velocity - initial velocity) / time.
