Forces and Motion

Front

What is friction?

Back

Friction is a force that resists the motion of one surface against another.

Front

How does mass affect motion?

Back

The greater the mass of an object, the less effect a force will have on its motion.

Front

What happens when two objects are pushed with the same force?

Back

The object with less mass will move the longest distance.

Front

Why is oil used in machines?

Back

Oil reduces the friction between the parts of the machine, allowing it to work faster.

Front

What occurs in a tug-of-war when both teams pull equally?

Back

The rope does not move because the forces are balanced.

Front

What is a force?

Back

A force is a push or pull that can cause an object to move, stop, or change direction.

Front

What is gravity?

Back

Gravity is a force that pulls objects toward each other, such as the Earth pulling us down.

Front

What is the relationship between force and motion?

Back

A force applied to an object can change its motion, including speed and direction.

Front

What is inertia?

Back

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

Front

What is the effect of increasing force on an object?

Back

Increasing the force applied to an object will increase its acceleration.
