Newton's Laws

Front

What is the net force?

Back

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

Front

What is average speed?

Back

Average speed is the total distance traveled divided by the total time taken. It gives an overall measure of how fast an object is moving.

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 (F=ma).

Front

What is an example of balancing forces?

Back

An example of balancing forces is a book resting on a table, where the force of gravity pulling it down is balanced by the normal force from the table pushing it up.

Front

What does 'For every action there is an equal and opposite reaction' mean?

Back

This means that for every force exerted by one object, there is a force of equal strength but in the opposite direction exerted by the second object.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist changes in its state of motion. An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net force.

Front

What is the difference between mass and weight?

Back

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

Front

What is the formula for calculating force?

Back

The formula for calculating force is F = ma, where F is force, m is mass, and a is acceleration.

Front

What is the principle of conservation of momentum?

Back

The principle of conservation of momentum states that in a closed system, the total momentum before an event is equal to the total momentum after the event.

Front

What is friction?

Back

Friction is a force that opposes the motion of an object. It occurs when two surfaces interact and can affect the acceleration of the object.
