What is Gravitational Potential Energy?

Back

Gravitational Potential Energy (GPE) is the energy an object possesses due to its position in a gravitational field, calculated as GPE = mgh, where m is mass, g is the acceleration due to gravity, and h is height.

Front

How do you calculate the maximum velocity of an object dropped from a height?

Back

The maximum velocity (v) of an object dropped from a height can be calculated using the formula v = √(2gh), where g is the acceleration due to gravity and h is the height.

Front

What is Newton's 1st Law of Motion?

Back

Newton's 1st Law states that an object at rest will remain at rest, and an object in motion will continue in motion with the same speed and in the same direction unless acted upon by a net external force.

Front

What is the formula for calculating acceleration?

Back

Acceleration (a) can be calculated using the formula a = F/m, where F is the net force applied to the object and m is the mass of the object.

Front

What is the unit of force in the International System of Units (SI)?

Back

The unit of force in the SI system is the Newton (N).

Front

What does a hockey puck sliding on frictionless ice demonstrate?

Back

It demonstrates Newton's 1st Law of Motion, as it continues to move at a constant velocity due to the absence of net external forces.

Front

What is the significance of the meniscus in measuring liquids?

Back

The meniscus is the curve at the surface of a liquid in a container, and it is important to read the measurement at the bottom of the meniscus for accuracy.

Front

What is the relationship between mass and weight?

Back

Weight (W) is the force exerted by gravity on an object and is calculated as W = mg, where m is mass and g is the acceleration due to gravity.

Front

What is kinetic energy?

Back

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

Front

What is the principle of conservation of energy?

Back

The principle of conservation of energy states that energy cannot be created or destroyed, only transformed from one form to another.
