What is static friction?

Back

Static friction is the force that keeps two objects at rest from moving when a force is applied. It occurs when two objects touch, and one or neither does not move.

What is the acceleration due to gravity?

Back

The acceleration due to gravity is 9.8 m/s², which is the rate at which objects accelerate towards the Earth when in free fall.

Front

Who was the first to study gravity and its effects?

Back

Isaac Newton was the first to study gravity and its effects, formulating the law of universal gravitation.

Front

What changes when an object is in motion?

Back

When an object is in motion, its position changes over time.

A person kicking a soccer ball is which Newton's law?

Back

A person kicking a soccer ball demonstrates Newton's second law, which states that the acceleration of an object is directly proportional to the net force acting on it.

Front

What is Newton's first law of motion?

Back

Newton's first law of motion states that an object at rest will remain at rest, and an object in motion will remain in motion at a constant velocity unless acted upon by a net external force.

Front

What is Newton's third law of motion?

Back

Newton's third law of motion states that for every action, there is an equal and opposite reaction.

Front

What is kinetic friction?

Back

Kinetic friction is the force that opposes the motion of two surfaces sliding past each other.

Front

What is the formula for calculating force?

Back

The formula for calculating force is F = m * a, where F is force, m is mass, and a is acceleration.

Front

What is the difference between mass and weight?

Back

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