Forces and Motion Concepts

Front

What is a balanced force?

Back

A balanced force occurs when two forces acting on an object are equal in size but opposite in direction, resulting in no change in motion.

Front

Give an example of a balanced force.

Back

An asteroid moving at a constant speed through space.

Front

What is an unbalanced force?

Back

An unbalanced force occurs when two forces acting on an object are not equal, causing the object to accelerate in the direction of the greater force.

Front

Why is a bowling ball harder to accelerate than a kickball?

Back

The bowling ball has more mass.

Front

What is the formula to calculate force?

Back

Force (F) = Mass (m) x Acceleration (a) or F = m * a.

Front

If a 6 N force causes a 2 m/s² acceleration, what is the mass of the object?

Back

3 kg.

Front

Who developed the Laws of Motion?

Back

Sir Isaac Newton.

Front

What is net force?

Back

Net force is the total force acting on an object after all the forces are combined.

Front

If the net force is 40 N to the right, what does this indicate?

Back

The object will accelerate to the right.

Front

What is inertia?

Back

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