Newtons Laws of Motion

Front

What is the net force?

Back

The net force is the total force acting on an object after all the forces are combined. It determines the object's acceleration.

Why is it harder for the boy in Image B to get down the hill?

Back

Friction makes it harder to move down the hill as it opposes the motion.

Front

What is the formula for force?

Back

Force = mass x acceleration (F = m x a) is used to calculate the force acting on an object.

What is the standard unit force is measured in?

Back

The standard unit of force is Newtons (N).

Front

What is Newton's First Law?

Back

An object in motion will stay in motion and an object at rest will stay at rest unless acted upon by an outside force.

Front

What is Newton's Second Law?

Back

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

Front

What is inertia?

Back

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

Front

What is friction?

Back

Friction is a force that opposes the motion of an object when it is in contact with another surface.

Front

What is the difference between mass and weight?

Back

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