Front

What is air resistance?

Back

Air resistance is a force that opposes the motion of an object through the air, acting in the opposite direction to the object's movement.

Front

What does Newton's 3rd Law state?

Back

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

Front

What happens when two skaters push off each other?

Back

They exert equal and opposite forces on each other, causing them to move away from each other.

Front

Why does a feather fall slower than a hammer when dropped?

Back

The feather falls slower due to air resistance, which affects it more than the hammer.

Front

What is the effect of unbalanced forces on an object?

Back

An object will move in the direction of the larger force when unbalanced forces act on it.

Front

What is a free-body diagram?

Back

A free-body diagram is a graphical representation used to visualize the forces acting on an object.

Front

What is the relationship between mass and gravity?

Back

Gravity pulls harder on objects with greater mass, resulting in a stronger gravitational force.

Front

What is the role of friction in motion?

Back

Friction is a force that opposes the relative motion of two surfaces in contact.

Front

How does increasing surface area affect air resistance?

Back

Increasing surface area increases air resistance, making it harder for an object to move through the air.

Front

What is the difference between balanced and unbalanced forces?

Back

Balanced forces result in no change in motion, while unbalanced forces cause an object to accelerate in the direction of the net force.
