Front

What is a force?

Back

A force is a push or pull that can change the motion of an object.

Front

What is friction?

Back

Friction is a force that opposes motion between two surfaces that are in contact.

Front

How does a small push move a large object?

Back

A small push can unbalance the forces acting on an object, allowing it to move.

Front

What is the relationship between force and motion?

Back

A force applied to an object can cause it to start moving, stop moving, or change 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 formula for speed?

Back

Speed = Distance ÷ Time.
