newtons laws

Front

What is the net force?

Back

The net force is the overall force acting on an object when all the individual forces are combined. It determines the object's motion.

Front

What does Newton's First Law state?

Back

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

Front

Which law of motion states that for anything to move, you must apply an unbalanced force?

Back

Newton's First Law of Motion.

Front

Calculate the net force shown in the diagram: 5 N to the right and 4 N to the left.

Back

Net force = 5 N - 4 N = 1 N to the right.

Front

If two boys are pulling with the same amount of force, what will happen?

Back

They will not move at all because the forces are balanced.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. It is directly related to the mass of the object.

Front

What is the formula for calculating force?

Back

Force (F) = mass (m) × acceleration (a).

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object. It can be caused by a change in speed or direction.

Front

What does Newton's Second Law state?

Back

Newton's Second Law states that the acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass.

Front

What is the relationship between mass and weight?

Back

Weight is the force exerted by gravity on an object, calculated as Weight (W) = mass (m) × gravitational acceleration (g).
