Newtons First Law REVIEW

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 at a constant velocity unless acted upon by a net external force.

Front

What is inertia?

Back

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

Front

What happens to a rider on a horse when the horse suddenly starts running?

Back

The lower body of the rider moves forward with the horse, but the inertia of rest keeps the upper body at rest, causing the rider to fall.

Front

What is net force?

Back

Net force is the vector sum of all the forces acting on an object.

Front

If two objects collide, how does mass affect the force exerted?

Back

The heavier object exerts more force upon collision compared to a lighter object.

Front

What is the relationship between mass and inertia?

Back

The greater the mass of an object, the greater its inertia.

Front

What is an example of an object at rest?

Back

A book lying on a table.

Front

What is an example of an object in motion?

Back

A car driving down the road.

Front

What does it mean for an object to be in equilibrium?

Back

An object is in equilibrium when the net force acting on it is zero.

Front

How does friction affect motion?

Back

Friction opposes the motion of an object, acting as a force that slows it down.
