Force and Motion

Front

What is the Law of Inertia?

Back

Newton's 1st Law of Motion states that an object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

How does mass affect the motion of an object?

Back

The greater the mass of an object, the greater the force required to move it.

Front

What force causes leaves to fall to the ground after being tossed in the air?

Back

Gravity is the force that causes the leaves to land on the ground.

Front

Why does a car use less force on a concrete road compared to a dirt road?

Back

The dirt road has more friction because its surface is not smooth, requiring more force to move the car.

Front

What does it mean when forces are balanced in a tug-of-war?

Back

Balanced forces mean that the net force acting on the object is zero, resulting in no movement.

Front

What is friction?

Back

Friction is the force that opposes the motion of an object when it is in contact with another surface.

Front

What is Newton's 2nd Law of Motion?

Back

Newton's 2nd 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 the difference between mass and weight?

Back

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

Front

What is an example of an unbalanced force?

Back

An example of an unbalanced force is when one team pulls harder than the other in a tug-of-war, causing the flag to move.

Front

What is the role of gravity in motion?

Back

Gravity is a force that pulls objects toward each other, influencing their motion and causing them to fall.
