Newton's Laws

Front

What does 'Forces come in pairs' represent?

Back

Newton's 3rd law states that for every action, there is an equal and opposite reaction.

Front

What does an unbalanced force mean for an object?

Back

An unbalanced force means that an object is changing its motion.

Front

What is inertia?

Back

Inertia is the tendency of an object to resist a change in motion.

Front

What determines the amount of friction between two objects?

Back

The amount of friction is determined by the force and roughness between the surfaces.

Front

What is the relationship between mass and inertia?

Back

Objects with greater mass also have greater inertia.

Front

What is Newton's 1st law of motion?

Back

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

Front

What is Newton's 2nd law of motion?

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 for calculating force?

Back

Force (F) is calculated using the formula F = mass (m) × acceleration (a).

Front

What is the effect of friction on motion?

Back

Friction opposes the motion of objects, making it harder for them to move.

Front

What is the role of gravity in motion?

Back

Gravity is a force that pulls objects toward each other, affecting their motion.
