What happens to a moving object if the resultant force on it is zero?
If the resultant force on an object is zero it keeps moving.
1 of 9
What happens to a moving object if the resultant force on it is not zero?
If the resultant force on an object is not zero it speeds up in the direction of the resultant force.
2 of 9
If we double the resultant force applied to an object, what happens to its acceleration?
If we double the resultant force applied to an object its acceleration doubles.
3 of 9
What force is needed to give an acceleration of 2 m/s2 to a 4 kg box?
force = 4 × 2 = 8 N.
4 of 9
4 N is applied to a 2 kg object. What is its acceleration?
Acceleration = 4 ÷ 2 = 2 m/s2.
5 of 9
What happens to a moving object if the resultant force on it is not zero?
It accelerates towards the resultant force.
6 of 9
If we double the resultant force applied to an object, what happens to its acceleration?
The object's acceleration doubles.
7 of 9
What does a horizontal line on a velocity-time graph represent?
A horizontal line on a velocity-time graph represents constant velocity.
8 of 9
