Force and Motion

Front

What type of force is needed to overcome the inertia of an object?

Back

Unbalanced force.

Front

What force opposes the motion of any object?

Back

Friction.

Front

What force is responsible for a soccer ball slowing down after being kicked?

Back

Friction, as the ground rubs against the ball, slowing it down.

Front

In which situation are the forces operating on an object unbalanced?

Back

When a baseball falls at a faster and faster speed.

Front

What causes the speed of an object to change?

Back

An unbalanced force.

Front

Define inertia in the context of motion.

Back

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

Front

What is the relationship between mass and inertia?

Back

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

Front

What is the effect of balanced forces on an object's motion?

Back

Balanced forces do not change the motion of an object.

Front

How does friction affect the motion of an object?

Back

Friction opposes the motion, causing the object to slow down or stop.

Front

What is the formula for calculating force?

Back

Force = mass × acceleration (F = ma).
