The Second Law of Motion

Front

Any change in velocity is called ___________.

Back

acceleration

Front

Fnet = mass * acceleration. A 20 kg bike accelerates to the left at 10 m/s². What is the net force acting upon it?

Back

200 Newtons to the left

Front

What is the unit for acceleration?

Back

m/s²

Front

A unbalanced force on an object means that an object is ___________.

Back

changing its motion

Front

What unit do we measure force in?

Back

Newtons

Front

What is the Second 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.

Front

If a 10 kg object experiences a net force of 50 N, what is its acceleration?

Back

5 m/s²

Front

What does it mean if an object is in equilibrium?

Back

The net force acting on the object is zero.

Front

How does mass affect acceleration when a constant force is applied?

Back

Greater mass results in less acceleration.

Front

What is the formula to calculate force?

Back

Force = mass * acceleration
