What is the principle of action and reaction in Newton's laws?

Back

For every action, there is an equal and opposite reaction.

Front

Can you exert a force on an object without it exerting a force back on you?

Back

No, you cannot exert a force on anything unless it also exerts a force on you.

Front

When two objects collide, do they exert equal forces on each other?

Back

Yes, when two objects collide, they exert equal forces on each other.

Front

What happens to the forces when a heavy object hits a light object?

Back

The forces are equal, but the effects may differ due to their masses.

Front

Do forces occur in pairs?

Back

Yes, forces always occur in pairs.

Front

What is an example of a force pair?

Back

When you push against a wall, the wall pushes back against you with equal force.

Front

What is the relationship between mass and force in a collision?

Back

The force exerted is equal, but the acceleration may differ due to the mass of the objects.

Front

What is the definition of force?

Back

A force is a push or pull on an object that can cause it to change its motion.

Front

What is inertia?

Back

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

Front

What is the formula for calculating force?

Back

Force = mass x acceleration (F = ma).
