GCSE Physics - Newton’s Third Law #57

The video explains Newton's Third Law, which states that forces between two interacting objects are equal in magnitude and opposite in direction. It discusses how this principle applies to real-world scenarios, such as pushing a box, and how the mass of objects affects their movement. The video also touches on Newton's Second Law, explaining that acceleration is determined by the force applied and the mass of the object, highlighting why smaller objects tend to move more when equal forces are applied.

What does Newton's third law state about the forces between two interacting objects?

• They are neither equal in magnitude nor direction.

• They are both equal in magnitude and direction.

• They are equal in direction and opposite in magnitude.

• They are equal in magnitude and opposite in direction.

What is the force called that a box exerts back when you push it?

• Frictional force

• Tension force

• Gravitational force

• Normal contact force

Why is a smaller object more likely to move when interacting with a larger object?

• Because it has a higher mass.

• Because it has a lower mass.

• Because it exerts a greater force.

• Because it exerts a lesser force.

What happens when you push yourself off a wall?

• The wall moves backward.

• You move forward.

• Neither you nor the wall move.

• Both you and the wall move.

According to Newton's second law, what two factors determine an object's acceleration?

• Force and velocity

• Mass and velocity

• Force and mass

• Mass and distance
