AQA GCSE Newton's 1st Law(Physics)

Practice Question

1.State the definition of Newton’s 1st law.

An object will remain at rest or continue moving in a straight line at a constant speed unless acted upon by an external force.

2.What does Newton’s First Law of Motion state about an object at rest?

b) It will remain at rest unless acted on by an unbalanced force. (correct answer)

3.Which of the following is an example of balanced forces?

d) Both b and c. (correct answer)

 
4.What is inertia, and how does it relate to Newton’s First Law?
 
Inertia is the tendency of objects to continue in their state of rest or of uniform motion. 
 
Inertia explains why an object resists changes to its motion. For example, a stationary object doesn’t start moving on its own, and a moving object doesn’t stop or change direction without some force acting on it.
 
5.An object is sliding on a frictionless surface. If no external force acts on it, what will happen to the object’s motion?
 
The object will continue to slide along the frictionless surface at the same speed and in the same direction.
