Newtons 1st and 2nd Law

Front

What unit do we measure Force in?

Back

Newtons

Front

What is Newton's 1st Law?

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 Newton's 2nd Law?

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 the formula to calculate mass?

Back

m = f/a

Front

If a force of 26 N is exerted on two balls, one with a mass of 0.52 kg and the other with a mass of 0.78 kg, which ball will have the greater acceleration?

Back

The one with a mass of 0.52 kg will have the greatest acceleration.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion.

Front

What is the relationship between force, mass, and acceleration?

Back

Force equals mass times acceleration (F=ma).

Front

What happens to the acceleration of an object if the mass increases while the force remains constant?

Back

The acceleration decreases.

Front

What is the effect of gravity on objects in free fall?

Back

All objects in free fall accelerate downwards at the same rate due to gravity, regardless of their mass.

Front

What is static friction?

Back

Static friction is the force that keeps an object at rest and prevents it from moving.
