Friction is a force that opposes the motion of an object, helping to slow it down or stop it.

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 a balanced force?

Back

Balanced forces are equal in size and opposite in direction, resulting in no change in motion.

Front

What is an unbalanced force?

Back

Unbalanced forces are not equal and can cause an object to start moving, stop moving, or change direction.

Front

How does ramp height affect distance?

Back

Higher ramps give objects more potential energy, allowing them to roll further.

Front

What happens when you push a swing harder?

Back

The swing will go higher when pushed harder.

Front

How does friction help us move?

Back

Friction keeps us from slipping and sliding, allowing us to walk and run safely.

Front

What is the effect of mass on speed?

Back

The mass of an object can affect its speed, but in a frictionless environment, all objects fall at the same rate.

Front

What is mechanical advantage?

Back

Mechanical advantage is the factor by which a machine multiplies the force put into it.
