- Forces and their effects
- How are forces represented?
- By an arrow, ideally from where the force originates.
- What will happen if the resultant force acting on a stationary object is zero?
- The object will stay stationary
- What is a resultant force?
- A single force which replaces a number of forces all acting at a particular point. The resultant force has the same effect on the motion as all the forces acting together.
- What will happen if the resultant force acting on a moving object is zero?
- The object will move at the same speed and in the same direction
- What are the units of mass?
- Kilograms (kg), grams (g) or sometimes tonnes (1000kg)
- What is the unit for force?
- Newtons (N)
- How are force, mass and acceleration linked?
- Force = mass x accelerationF(N) = m (kg) x (m/s2)
- What will happen if the resultant force acting on a stationary object is not zero?
- The object will accelerate in the direction of the resultant force.
- What will happen if the resultant force acting on a moving object is not zero?
- The object will accelerate in the direction of the resultant force.
- What is the unit of acceleration?
- Metres per second squared (m/s2)
- How are forces represented?
