Newton Laws

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 with the same speed and in the same direction unless acted upon by an unbalanced force.

Front

What is Newton's Second Law of Motion?

Back

The acceleration of an object is directly proportional to the net force acting on it and inversely proportional to its mass. (F = ma)

Front

What is Newton's Third Law of Motion?

Back

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

Front

How do you calculate force?

Back

Force (F) is calculated using the formula F = ma, where m is mass and a is acceleration.

Front

What is net force?

Back

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

Front

What happens when forces are balanced?

Back

When forces are balanced, the net force is zero, and the object does not accelerate.

Front

What happens when forces are unbalanced?

Back

When forces are unbalanced, the net force is not zero, and the object will accelerate in the direction of the larger force.

Front

If a bike has a mass of 20 kg and accelerates at 10 m/s², what is the force applied?

Back

The force applied is 200 N (using F = ma).

Front

If an object experiences a net force of 1 N to the left, what can we say about the forces acting on it?

Back

The forces acting on it are unbalanced, resulting in a net force that causes acceleration to the left.

Front

If a force of 8 N is applied to the left and a force of 4 N is applied to the right, what is the net force?

Back

The net force is 4 N to the left, and the forces are unbalanced.
