Motion & Newton's Laws

Front

What is the tendency of an object to resist being moved or stopped?

Back

Inertia

Front

According to Newton's 2nd Law, if you pushed a wagon full of pumpkins, how would it accelerate compared to an empty wagon?

Back

It would accelerate less than an empty wagon.

Front

What is the formula for Newton's 2nd Law?

Back

Force = mass x acceleration (F=ma)

Front

What does Newton's 3rd Law state?

Back

For every action, there's an equal and opposite reaction.

Front

What is a push or a pull called?

Back

Force

Front

What is the first law of motion proposed by Newton?

Back

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

Front

What is the term for the force that opposes the motion of two surfaces in contact?

Back

Friction

Front

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

Back

Newton (N)

Front

What is the effect of gravity on an object in free fall?

Back

It accelerates the object downwards at approximately 9.81 m/s².

Front

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

Back

Acceleration is directly proportional to the net force acting on an object and inversely proportional to its mass.
