Category 2 Force and Motion

Front

What is potential energy?

Back

Potential energy is the energy stored in an object due to its position or configuration. It is greatest at the highest point in a system.

Front

What is the formula to calculate force?

Back

Force (F) is calculated using the formula F = mass (m) × acceleration (a).

Front

What is Newton's 2nd Law of Motion?

Back

Newton's 2nd Law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

What is kinetic energy?

Back

Kinetic energy is the energy of an object in motion, calculated using the formula KE = 1/2 mv², where m is mass and v is velocity.

Front

What does the 3rd Law of Motion state?

Back

The 3rd Law of Motion states that for every action, there is an equal and opposite reaction.

Front

What is the relationship between mass and acceleration in Newton's 2nd Law?

Back

In Newton's 2nd Law, as mass increases, acceleration decreases if the force remains constant.

Front

What is energy transformation?

Back

Energy transformation is the process of changing energy from one form to another, such as electrical energy to light energy in a lamp.

Front

What is the formula for calculating potential energy?

Back

Potential energy (PE) is calculated using the formula PE = mgh, where m is mass, g is acceleration due to gravity, and h is height.

Front

What is the difference between mass and weight?

Back

Mass is the amount of matter in an object, while weight is the force exerted by gravity on that mass.
