Force and Motion Review 1

Front

What is inertia?

Back

Inertia is the property of an object to resist changes in its state of motion. The greater the mass of an object, the greater its inertia.

Front

How does mass affect inertia?

Back

As mass increases, inertia increases.

Front

What is the net force?

Back

The net force is the total force acting on an object when all the individual forces are combined. It determines the object's acceleration.

Front

What happens when unbalanced forces act on an object?

Back

Unbalanced forces cause an object to accelerate in the direction of the net force.

Front

What is the relationship between force, mass, and acceleration?

Back

According to Newton's second law, force equals mass times acceleration (F = ma).

Front

What is the effect of applying a force in the opposite direction of motion?

Back

Applying a force in the opposite direction of motion will slow down the object.

Front

In a tug-of-war, what does it mean if one person wins?

Back

If one person wins, it means they applied a greater force than their opponent.

Front

What is the direction of motion for an object with a net force acting on it?

Back

The object will move in the direction of the net force.

Front

How does a train's motion affect a ball at rest inside it?

Back

When the train starts moving, the ball will appear to move in the opposite direction due to inertia.

Front

What is the formula for calculating net force?

Back

Net force = Sum of all forces acting on an object.
