Name that Force!
This type of force occurs when two surfaces rub against each other as they move.
Friction
What is the rate of change of velocity?
Acceleration
A push or pull acting on an object.
What is a force
Who invented gravity?
Trick question no one, nut Newton discovered it!
This force pulls objects toward the centre of the Earth
Gravity
The distance an object travels per unit of time.
Speed / Velocity
Engine force of a car is 1000N.
Friction is 200N
Air resistance is 250N
What is the Resultant force?
550N
How can you explain why you fly forward in a car when it suddenly stops?
What is inertia?
This is the force that pushes an object forward, often used to describe planes or rockets.
Thrust
A horizontal line on a distance–time graph shows.
No movement
Two forces acting in opposite directions with the same strength are called this.
What are balanced forces
According to this law, acceleration increases when force increases (if mass stays the same).
What is Newton’s Second Law
What force is caused by gravity acting on a mass?
Weight
Mass is measured in ?
Weight is measured in ?
Work is measured in ?
Acceleration is measured in ?
kg
N
J
m/s2
Magnetic, electrostatic and gravitational are non-contact forces. What separates the first two from the third?
They can attract and repel, gravitational only attracts
This law states that every action has an equal and opposite reaction.
What is Newton’s Third Law
The total force acting on an object after all forces are combined.
Net Force
What does the gradient on a distance-time graph show us?
Speed
I am underwater. Upthrust is 1000N and weight is 900N
What happens?
I move upwards
This law says objects stay at rest or keep moving unless acted on by an unbalanced force.
What is Newton's First Law
