Physics 2

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It can be positive (speeding up) or negative (slowing down).

Front

What does it mean to decelerate?

Back

Deceleration refers to the process of slowing down or reducing speed.

Front

What is Newton's 1st Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion at a constant velocity unless acted upon by a net external force.

Front

What is Newton's 2nd Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. (F = ma)

Front

What is Newton's 3rd Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

How do you calculate force?

Back

Force is calculated using the formula: Force = Mass x Acceleration (F = ma).

Front

What is the unit of force?

Back

The unit of force is the Newton (N).

Front

What is the acceleration of an object with a mass of 50 kg pushed with a force of 500 N?

Back

The acceleration is 10 m/s².

Front

What is constant speed?

Back

Constant speed means that an object covers equal distances in equal intervals of time, regardless of how small the time intervals are.

Front

What is the difference between speed and velocity?

Back

Speed is a scalar quantity that refers to how fast an object is moving, while velocity is a vector quantity that includes both speed and direction.
