Force and Motion Review

Front

What is friction?

Back

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

Front

Why is friction important?

Back

Friction is important because it allows us to walk without slipping, helps vehicles stop, and enables objects to stay in place.

Front

What is Newton's First Law of Motion?

Back

An object at rest stays at rest, and an object in motion stays in motion unless acted upon by a net external force.

Front

What is Newton's Second Law of Motion?

Back

F=ma, which means the force acting on an object is equal to the mass of the object multiplied by its acceleration.

Front

What is Newton's Third Law of Motion?

Back

For every action, there is an equal and opposite reaction.

Front

What is inertia?

Back

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

Front

What is net force?

Back

Net force is the overall force acting on an object when all the individual forces are combined.

Front

How do you calculate net force?

Back

Net force can be calculated by adding all the forces acting on an object, taking into account their direction.

Front

What is acceleration?

Back

Acceleration is the rate of change of velocity of an object.

Front

What is the formula for acceleration?

Back

Acceleration (a) = (final velocity - initial velocity) / time.
