Newtons 1-3 laws of motion

What does velocity mean?

• The change in velocity of an object.

• The speed of an object in a certain direction.

• The amount of matter in an object.

• A push or pull in a specific direction.

What is Newton's second law of motion about?

• The speed of an object in a certain direction.

• The change in velocity of an object.

• The amount of matter in an object.

• The relationship between force, mass, and acceleration.

What happens to the velocity of an object when a force is applied to it? (a)  

• It stays the same.

• It decreases.

• It increases.

• It changes in a random direction.

What does the equation F = m * a represent?

• The relationship between force, mass, and acceleration.

• The speed of an object in a certain direction.

• The change in velocity of an object.

• The amount of matter in an object.

What is acceleration?

• A push or pull in a specific direction.

• The speed of an object in a certain direction.

• The change in velocity of an object.

• The amount of matter in an object.
